The #GAppLaunchContext::launch-failed signal is emitted when a #GAppInfo launch

<description>
The #GAppLaunchContext::launch-started signal is emitted when a #GAppInfo is

GVariant dictionary mapping strings to variants (ie `a{sv}`), which
contains additional, platform-specific data about this launch. On
UNIX, at least the `startup-notification-id` keys will be
present.

The value of the `startup-notification-id` key (type `s`) is a startup
notification ID corresponding to the format from the [startup-notification
specification](https://specifications.freedesktop.org/startup-notification-spec/startup-notification-0.1.txt).
It allows tracking the progress of the launchee through startup.

It is guaranteed that this signal is followed by either a #GAppLaunchContext::launched or
#GAppLaunchContext::launch-failed signal.

Because a launch operation may involve spawning multiple instances of the
target application, you should expect this signal to be emitted multiple
times, one for each spawned instance.

<description>
The #GAppLaunchContext::launched signal is emitted when a #GAppInfo is successfully
launched.

Because a launch operation may involve spawning multiple instances of the
target application, you should expect this signal to be emitted multiple
times, one time for each spawned instance.

The @platform_data is an GVariant dictionary mapping
strings to variants (ie `a{sv}`), which contains additional,
platform-specific data about this launch. On UNIX, at least the
`pid` and `startup-notification-id` keys will be present.

Since 2.72 the `pid` may be 0 if the process id wasn't known (for
example if the process was launched via D-Bus). The `pid` may not be
set at all in subsequent releases.

On Windows, `pid` is guaranteed to be valid only for the duration of the
#GAppLaunchContext::launched signal emission; after the signal is emitted,
GLib will call g_spawn_close_pid(). If you need to keep the #GPid after the
signal has been emitted, then you can duplicate `pid` using `DuplicateHandle()`.

</return>
</signal>

<signal name="GApplication::handle-local-options">
<description>
The ::handle-local-options signal is emitted on the local instance
after the parsing of the commandline options has occurred.

You can add options to be recognised during commandline option
parsing using g_application_add_main_option_entries() and
g_application_add_option_group().

Signal handlers can inspect @options (along with values pointed to
from the @arg_data of an installed #GOptionEntrys) in order to
decide to perform certain actions, including direct local handling
(which may be useful for options like --version).

In the event that the application is marked
%G_APPLICATION_HANDLES_COMMAND_LINE the &quot;normal processing&quot; will
send the @options dictionary to the primary instance where it can be
read with g_application_command_line_get_options_dict().  The signal
handler can modify the dictionary before returning, and the
modified dictionary will be sent.

In the event that %G_APPLICATION_HANDLES_COMMAND_LINE is not set,
&quot;normal processing&quot; will treat the remaining uncollected command
line arguments as filenames or URIs.  If there are no arguments,
the application is activated by g_application_activate().  One or
more arguments results in a call to g_application_open().

If you want to handle the local commandline arguments for yourself
by converting them to calls to g_application_open() or
g_action_group_activate_action() then you must be sure to register
the application first.  You should probably not call
g_application_activate() for yourself, however: just return -1 and
allow the default handler to do it for you.  This will ensure that
the `--gapplication-service` switch works properly (i.e. no activation
in that case).

Note that this signal is emitted from the default implementation of
local_command_line().  If you override that function and don't
chain up then this signal will never be emitted.

You can override local_command_line() if you need more powerful
capabilities than what is provided here, but this should not
normally be required.

<signal name="GCancellable::cancelled">
<description>
Emitted when the operation has been cancelled.

Can be used by implementations of cancellable operations. If the
operation is cancelled from another thread, the signal will be
emitted in the thread that cancelled the operation, not the
thread that is running the operation.

Note that disconnecting from this signal (or any signal) in a
multi-threaded program is prone to race conditions. For instance
it is possible that a signal handler may be invoked even after
a call to g_signal_handler_disconnect() for that handler has
already returned.

There is also a problem when cancellation happens right before
connecting to the signal. If this happens the signal will
unexpectedly not be emitted, and checking before connecting to
the signal leaves a race condition where this is still happening.

In order to make it safe and easy to connect handlers there
are two helper functions: g_cancellable_connect() and
g_cancellable_disconnect() which protect against problems
like this.

An example of how to us this:
|[&lt;!-- language=&quot;C&quot; --&gt;
// Make sure we don't do unnecessary work if already cancelled
if (g_cancellable_set_error_if_cancelled (cancellable, error))
return;

// Set up all the data needed to be able to handle cancellation
// of the operation
my_data = my_data_new (...);

id = 0;
if (cancellable)
id = g_cancellable_connect (cancellable,
G_CALLBACK (cancelled_handler)
data, NULL);

// cancellable operation here...

g_cancellable_disconnect (cancellable, id);

// cancelled_handler is never called after this, it is now safe
// to free the data
my_data_free (my_data);  
]|

Note that the cancelled signal is emitted in the thread that
the user cancelled from, which may be the main thread. So, the
cancellable signal should not do something that can block.

<signal name="GDBusConnection::closed">
<description>
Emitted when the connection is closed.

The cause of this event can be

- If g_dbus_connection_close() is called. In this case
@remote_peer_vanished is set to %FALSE and @error is %NULL.

- If the remote peer closes the connection. In this case
@remote_peer_vanished is set to %TRUE and @error is set.

- If the remote peer sends invalid or malformed data. In this
case @remote_peer_vanished is set to %FALSE and @error is set.

Upon receiving this signal, you should give up your reference to
@connection. You are guaranteed that this signal is emitted only
once.

<property name="GDBusConnection:guid">
<description>
The GUID of the peer performing the role of server when
authenticating.

If you are constructing a #GDBusConnection and pass
%G_DBUS_CONNECTION_FLAGS_AUTHENTICATION_SERVER in the
#GDBusConnection:flags property then you **must** also set this
property to a valid guid.

If you are constructing a #GDBusConnection and pass
%G_DBUS_CONNECTION_FLAGS_AUTHENTICATION_CLIENT in the
#GDBusConnection:flags property you will be able to read the GUID
of the other peer here after the connection has been successfully
initialized.

Note that the
[D-Bus specification](https://dbus.freedesktop.org/doc/dbus-specification.html#addresses)
uses the term ‘UUID’ to refer to this, whereas GLib consistently uses the
term ‘GUID’ for historical reasons.

Despite its name, the format of #GDBusConnection:guid does not follow

<signal name="GDBusInterfaceSkeleton::g-authorize-method">
<description>
Emitted when a method is invoked by a remote caller and used to
determine if the method call is authorized.

Note that this signal is emitted in a thread dedicated to
handling the method call so handlers are allowed to perform
blocking IO. This means that it is appropriate to call e.g.
[polkit_authority_check_authorization_sync()](http://hal.freedesktop.org/docs/polkit/PolkitAuthority.html#polkit-authority-check-authorization-sync)
with the
[POLKIT_CHECK_AUTHORIZATION_FLAGS_ALLOW_USER_INTERACTION](http://hal.freedesktop.org/docs/polkit/PolkitAuthority.html#POLKIT-CHECK-AUTHORIZATION-FLAGS-ALLOW-USER-INTERACTION:CAPS)
flag set.

If %FALSE is returned then no further handlers are run and the
signal handler must take a reference to @invocation and finish
handling the call (e.g. return an error via
g_dbus_method_invocation_return_error()).

Otherwise, if %TRUE is returned, signal emission continues. If no
handlers return %FALSE, then the method is dispatched. If
@interface has an enclosing #GDBusObjectSkeleton, then the
#GDBusObjectSkeleton::authorize-method signal handlers run before
the handlers for this signal.

The default class handler just returns %TRUE.

Please note that the common case is optimized: if no signals
handlers are connected and the default class handler isn't
overridden (for both @interface and the enclosing
#GDBusObjectSkeleton, if any) and #GDBusInterfaceSkeleton:g-flags does
not have the
%G_DBUS_INTERFACE_SKELETON_FLAGS_HANDLE_METHOD_INVOCATIONS_IN_THREAD
flags set, no dedicated thread is ever used and the call will be
handled in the same thread as the object that @interface belongs
to was exported in.

<description>
What steps to perform when validating a certificate received from

GLib guarantees that if certificate verification fails, at least one
flag will be set, but it does not guarantee that all possible flags
will be set. Accordingly, you may not safely decide to ignore any
particular type of error. For example, it would be incorrect to mask
%G_TLS_CERTIFICATE_EXPIRED if you want to allow expired certificates,
because this could potentially be the only error flag set even if
other problems exist with the certificate. Therefore, there is no
safe way to use this property. This is not a horrible problem,
though, because you should not be attempting to ignore validation
errors anyway. If you really must ignore TLS certificate errors,
connect to #GDtlsConnection::accept-certificate.

Since: 2.48

Deprecated: 2.74: Do not attempt to ignore validation errors.

</description>
</property>

<signal name="GDtlsConnection::accept-certificate">
<description>
Emitted during the TLS handshake after the peer certificate has
been received. You can examine @peer_cert's certification path by
calling g_tls_certificate_get_issuer() on it.

For a client-side connection, @peer_cert is the server's
certificate, and the signal will only be emitted if the
certificate was not acceptable according to @conn's
#GDtlsClientConnection:validation_flags. If you would like the
certificate to be accepted despite @errors, return %TRUE from the
signal handler. Otherwise, if no handler accepts the certificate,
the handshake will fail with %G_TLS_ERROR_BAD_CERTIFICATE.

GLib guarantees that if certificate verification fails, this signal
will be emitted with at least one error will be set in @errors, but
it does not guarantee that all possible errors will be set.
Accordingly, you may not safely decide to ignore any particular
type of error. For example, it would be incorrect to ignore
%G_TLS_CERTIFICATE_EXPIRED if you want to allow expired
certificates, because this could potentially be the only error flag
set even if other problems exist with the certificate.

For a server-side connection, @peer_cert is the certificate
presented by the client, if this was requested via the server's
#GDtlsServerConnection:authentication_mode. On the server side,
the signal is always emitted when the client presents a
certificate, and the certificate will only be accepted if a
handler returns %TRUE.

Note that if this signal is emitted as part of asynchronous I/O
in the main thread, then you should not attempt to interact with
the user before returning from the signal handler. If you want to
let the user decide whether or not to accept the certificate, you
would have to return %FALSE from the signal handler on the first
attempt, and then after the connection attempt returns a
%G_TLS_ERROR_BAD_CERTIFICATE, you can interact with the user, and
if the user decides to accept the certificate, remember that fact,
create a new connection, and return %TRUE from the signal handler
the next time.

If you are doing I/O in another thread, you do not
need to worry about this, and can simply block in the signal
handler until the UI thread returns an answer.

<property name="GDtlsConnection:database">
<description>
The certificate database to use when verifying this TLS connection.
If no certificate database is set, then the default database will be
used. See g_tls_backend_get_default_database().

When using a non-default database, #GDtlsConnection must fall back to using
the #GTlsDatabase to perform certificate verification using
g_tls_database_verify_chain(), which means certificate verification will
not be able to make use of TLS session context. This may be less secure.
For example, if you create your own #GTlsDatabase that just wraps the
default #GTlsDatabase, you might expect that you have not changed anything,
but this is not true because you may have altered the behavior of
#GDtlsConnection by causing it to use g_tls_database_verify_chain(). See the
documentation of g_tls_database_verify_chain() for more details on specific
security checks that may not be performed. Accordingly, setting a
non-default database is discouraged except for specialty applications with

GLib guarantees that if certificate verification fails, at least
one error will be set, but it does not guarantee that all possible
errors will be set. Accordingly, you may not safely decide to
ignore any particular type of error. For example, it would be
incorrect to mask %G_TLS_CERTIFICATE_EXPIRED if you want to allow

<signal name="GFileMonitor::changed">
<description>
Emitted when @file has been changed.

If using %G_FILE_MONITOR_WATCH_MOVES on a directory monitor, and
the information is available (and if supported by the backend),
@event_type may be %G_FILE_MONITOR_EVENT_RENAMED,
%G_FILE_MONITOR_EVENT_MOVED_IN or %G_FILE_MONITOR_EVENT_MOVED_OUT.

In all cases @file will be a child of the monitored directory.  For
renames, @file will be the old name and @other_file is the new
name.  For &quot;moved in&quot; events, @file is the name of the file that
appeared and @other_file is the old name that it was moved from (in
another directory).  For &quot;moved out&quot; events, @file is the name of
the file that used to be in this directory and @other_file is the
name of the file at its new location.

It makes sense to treat %G_FILE_MONITOR_EVENT_MOVED_IN as
equivalent to %G_FILE_MONITOR_EVENT_CREATED and
%G_FILE_MONITOR_EVENT_MOVED_OUT as equivalent to
%G_FILE_MONITOR_EVENT_DELETED, with extra information.
%G_FILE_MONITOR_EVENT_RENAMED is equivalent to a delete/create
pair.  This is exactly how the events will be reported in the case
that the %G_FILE_MONITOR_WATCH_MOVES flag is not in use.

If using the deprecated flag %G_FILE_MONITOR_SEND_MOVED flag and @event_type is
%G_FILE_MONITOR_EVENT_MOVED, @file will be set to a #GFile containing the
old path, and @other_file will be set to a #GFile containing the new path.

In all the other cases, @other_file will be set to #NULL.

<signal name="GMenuModel::items-changed">
<description>
Emitted when a change has occurred to the menu.

The only changes that can occur to a menu is that items are removed
or added.  Items may not change (except by being removed and added
back in the same location).  This signal is capable of describing
both of those changes (at the same time).

The signal means that starting at the index @position, @removed
items were removed and @added items were added in their place.  If
@removed is zero then only items were added.  If @added is zero
then only items were removed.

As an example, if the menu contains items a, b, c, d (in that
order) and the signal (2, 1, 3) occurs then the new composition of
the menu will be a, b, _, _, _, d (with each _ representing some
new item).

Signal handlers may query the model (particularly the added items)
and expect to see the results of the modification that is being
reported.  The signal is emitted after the modification.

<description>
Whether the network is considered available. That is, whether the

Real-world networks are of course much more complicated than
this; the machine may be connected to a wifi hotspot that
requires payment before allowing traffic through, or may be
connected to a functioning router that has lost its own upstream
connectivity. Some hosts might only be accessible when a VPN is
active. Other hosts might only be accessible when the VPN is
not active. Thus, it is best to use g_network_monitor_can_reach()
or g_network_monitor_can_reach_async() to test for reachability
on a host-by-host basis. (On the other hand, when the property is
%FALSE, the application can reasonably expect that no remote
hosts at all are reachable, and should indicate this to the user
in its UI.)

Whether the network is considered metered. That is, whether the

might be billed by the amount of data transmitted, or there might be a
quota on the amount of traffic per month. This is typical with tethered
connections (3G and 4G) and in such situations, bandwidth intensive
applications may wish to avoid network activity where possible if it will

For most use cases it is more appropriate to use the &quot;changed&quot; signal.

In the event that the change event applies to one or more specified

event that the change event applies to the #GSettings object as a
whole (ie: potentially every key has been changed) then @keys will

&quot;writable-changed&quot; signal.  For most use cases it is more

In the event that the writability change applies only to a single

@key will be 0.

The default handler for this signal invokes the &quot;writable-changed&quot;

@parameter will always be of the expected type, i.e. the parameter type

Since GLib 2.40, if no handler is connected to this signal then the

type is to toggle them via the #GSimpleAction::change-state signal.
For stateful actions where the state type is equal to the parameter

@value will always be of the correct state type, i.e. the type of the
initial state passed to g_simple_action_new_stateful(). If an incorrect
type is given when requesting to change the state, this signal is not
emitted.

If no handler is connected to this signal then the default
behaviour is to call g_simple_action_set_state() to set the state
to the requested value. If you connect a signal handler then no
default action is taken. If the state should change then you must
call g_simple_action_set_state() from the handler.

An example of a 'change-state' handler:
|[&lt;!-- language=&quot;C&quot; --&gt;
static void
change_volume_state (GSimpleAction *action,
GVariant      *value,
gpointer       user_data)

requested = g_variant_get_int32 (value);

// Volume only goes from 0 to 10
if (0 &lt;= requested &amp;&amp; requested &lt;= 10)
g_simple_action_set_state (action, value);
}

It could set it to any value at all, or take some other action.

<property name="GSimpleProxyResolver:ignore-hosts">
<description>
A list of hostnames and IP addresses that the resolver should

Entries can be in one of 4 formats:

- A hostname, such as &quot;example.com&quot;, &quot;.example.com&quot;, or
&quot;*.example.com&quot;, any of which match &quot;example.com&quot; or
any subdomain of it.

- An IPv4 or IPv6 address, such as &quot;192.168.1.1&quot;,
which matches only that address.

- A hostname or IP address followed by a port, such as
&quot;example.com:80&quot;, which matches whatever the hostname or IP
address would match, but only for URLs with the (explicitly)
indicated port. In the case of an IPv6 address, the address
part must appear in brackets: &quot;[::1]:443&quot;

- An IP address range, given by a base address and prefix length,
such as &quot;fe80::/10&quot;, which matches any address in that range.

Note that when dealing with Unicode hostnames, the matching is
done against the ASCII form of the name.

Also note that hostname exclusions apply only to connections made
to hosts identified by name, and IP address exclusions apply only
to connections made to hosts identified by address. That is, if
example.com has an address of 192.168.1.1, and the :ignore-hosts list
contains only &quot;192.168.1.1&quot;, then a connection to &quot;example.com&quot;
(eg, via a #GNetworkAddress) will use the proxy, and a connection to
&quot;192.168.1.1&quot; (eg, via a #GInetSocketAddress) will not.

These rules match the &quot;ignore-hosts&quot;/&quot;noproxy&quot; rules most
commonly used by other applications.

connected.  Since GLib 2.40, you can access the remote
address via g_socket_connection_get_remote_address().

- %G_SOCKET_CLIENT_CONNECTED: @client has successfully connected
to a remote host. @connection is the connected #GSocketConnection.

- %G_SOCKET_CLIENT_PROXY_NEGOTIATING: @client is about to negotiate
with a proxy to get it to connect to @connectable. @connection is
the #GSocketConnection to the proxy server.

- %G_SOCKET_CLIENT_PROXY_NEGOTIATED: @client has negotiated a
connection to @connectable through a proxy server. @connection is
the stream returned from g_proxy_connect(), which may or may not
be a #GSocketConnection.

- %G_SOCKET_CLIENT_TLS_HANDSHAKING: @client is about to begin a TLS
handshake. @connection is a #GTlsClientConnection.

- %G_SOCKET_CLIENT_TLS_HANDSHAKED: @client has successfully completed
the TLS handshake. @connection is a #GTlsClientConnection.

- %G_SOCKET_CLIENT_COMPLETE: @client has either successfully connected
to @connectable (in which case @connection is the #GSocketConnection
that it will be returning to the caller) or has failed (in which
case @connection is %NULL and the client is about to return an error).

Each event except %G_SOCKET_CLIENT_COMPLETE may be emitted
multiple times (or not at all) for a given connectable (in
particular, if @client ends up attempting to connect to more than
one address). However, if @client emits the #GSocketClient::event
signal at all for a given connectable, then it will always emit
it with %G_SOCKET_CLIENT_COMPLETE when it is done.

Note that there may be additional #GSocketClientEvent values in
the future; unrecognized @event values should be ignored.

<property name="GSocketClient:tls-validation-flags">
<description>
The TLS validation flags used when creating TLS connections. The
default value is %G_TLS_CERTIFICATE_VALIDATE_ALL.

GLib guarantees that if certificate verification fails, at least one
flag will be set, but it does not guarantee that all possible flags
will be set. Accordingly, you may not safely decide to ignore any
particular type of error. For example, it would be incorrect to mask
%G_TLS_CERTIFICATE_EXPIRED if you want to allow expired certificates,
because this could potentially be the only error flag set even if
other problems exist with the certificate. Therefore, there is no
safe way to use this property. This is not a horrible problem,
though, because you should not be attempting to ignore validation
errors anyway. If you really must ignore TLS certificate errors,
connect to the #GSocketClient::event signal, wait for it to be
emitted with %G_SOCKET_CLIENT_TLS_HANDSHAKING, and use that to
connect to #GTlsConnection::accept-certificate.

why an issuer certificate cannot be naively assumed to be part of the
the certification path (though GLib's TLS backends may not follow the
path building strategies outlined in this RFC). Due to the complexity
of certification path building, GLib does not provide any way to know

<property name="GTlsClientConnection:validation-flags">
<description>
What steps to perform when validating a certificate received from
a server. Server certificates that fail to validate in any of the
ways indicated here will be rejected unless the application
overrides the default via #GTlsConnection::accept-certificate.

GLib guarantees that if certificate verification fails, at least one
flag will be set, but it does not guarantee that all possible flags
will be set. Accordingly, you may not safely decide to ignore any
particular type of error. For example, it would be incorrect to mask
%G_TLS_CERTIFICATE_EXPIRED if you want to allow expired certificates,
because this could potentially be the only error flag set even if
other problems exist with the certificate. Therefore, there is no
safe way to use this property. This is not a horrible problem,
though, because you should not be attempting to ignore validation
errors anyway. If you really must ignore TLS certificate errors,
connect to #GTlsConnection::accept-certificate.

Since: 2.28

Deprecated: 2.72: Do not attempt to ignore validation errors.

</description>
</property>

<signal name="GTlsConnection::accept-certificate">
<description>
Emitted during the TLS handshake after the peer certificate has
been received. You can examine @peer_cert's certification path by
calling g_tls_certificate_get_issuer() on it.

For a client-side connection, @peer_cert is the server's
certificate, and the signal will only be emitted if the
certificate was not acceptable according to @conn's
#GTlsClientConnection:validation_flags. If you would like the
certificate to be accepted despite @errors, return %TRUE from the
signal handler. Otherwise, if no handler accepts the certificate,
the handshake will fail with %G_TLS_ERROR_BAD_CERTIFICATE.

GLib guarantees that if certificate verification fails, this signal
will be emitted with at least one error will be set in @errors, but
it does not guarantee that all possible errors will be set.
Accordingly, you may not safely decide to ignore any particular
type of error. For example, it would be incorrect to ignore
%G_TLS_CERTIFICATE_EXPIRED if you want to allow expired
certificates, because this could potentially be the only error flag
set even if other problems exist with the certificate.

For a server-side connection, @peer_cert is the certificate
presented by the client, if this was requested via the server's
#GTlsServerConnection:authentication_mode. On the server side,
the signal is always emitted when the client presents a
certificate, and the certificate will only be accepted if a
handler returns %TRUE.

Note that if this signal is emitted as part of asynchronous I/O
in the main thread, then you should not attempt to interact with
the user before returning from the signal handler. If you want to
let the user decide whether or not to accept the certificate, you
would have to return %FALSE from the signal handler on the first
attempt, and then after the connection attempt returns a
%G_TLS_ERROR_BAD_CERTIFICATE, you can interact with the user, and
if the user decides to accept the certificate, remember that fact,
create a new connection, and return %TRUE from the signal handler
the next time.

If you are doing I/O in another thread, you do not
need to worry about this, and can simply block in the signal
handler until the UI thread returns an answer.

<property name="GTlsConnection:database">
<description>
The certificate database to use when verifying this TLS connection.
If no certificate database is set, then the default database will be
used. See g_tls_backend_get_default_database().

When using a non-default database, #GTlsConnection must fall back to using
the #GTlsDatabase to perform certificate verification using
g_tls_database_verify_chain(), which means certificate verification will
not be able to make use of TLS session context. This may be less secure.
For example, if you create your own #GTlsDatabase that just wraps the
default #GTlsDatabase, you might expect that you have not changed anything,
but this is not true because you may have altered the behavior of
#GTlsConnection by causing it to use g_tls_database_verify_chain(). See the
documentation of g_tls_database_verify_chain() for more details on specific
security checks that may not be performed. Accordingly, setting a

If the #GActionGroup implementation supports asynchronous remote
activation over D-Bus, this call may return before the relevant
D-Bus traffic has been sent, or any replies have been received. In
order to block on such asynchronous activation calls,
g_dbus_connection_flush() should be called prior to the code, which
depends on the result of the action activation. Without flushing
the D-Bus connection, there is no guarantee that the action would
have been activated.

The following code which runs in a remote app instance, shows an
example of a &quot;quit&quot; action being activated on the primary app
instance over D-Bus. Here g_dbus_connection_flush() is called
before `exit()`. Without g_dbus_connection_flush(), the &quot;quit&quot; action
may fail to be activated on the primary instance.

g_action_group_get_action_state_type(),
g_action_group_get_action_state_hint() and
g_action_group_get_action_state() with a single function call.

This provides two main benefits.

The first is the improvement in efficiency that comes with not having
to perform repeated lookups of the action in order to discover
different things about it.  The second is that implementing
#GActionGroup can now be done by only overriding this one virtual
function.

The interface provides a default implementation of this function that
calls the individual functions, as required, to fetch the
information.  The interface also provides default implementations of
those functions that call this function.  All implementations,
therefore, must override either this function or all of the others.

If the action exists, %TRUE is returned and any of the requested
fields (as indicated by having a non-%NULL reference passed in) are
filled.  If the action doesn't exist, %FALSE is returned and the

<function name="g_action_parse_detailed_name">
<description>
Parses a detailed action name into its separate name and target
components.

Detailed action names can have three formats.

The first format is used to represent an action name with no target
value and consists of just an action name containing no whitespace
nor the characters ':', '(' or ')'.  For example: &quot;app.action&quot;.

The second format is used to represent an action with a target value
that is a non-empty string consisting only of alphanumerics, plus '-'
and '.'.  In that case, the action name and target value are
separated by a double colon (&quot;::&quot;).  For example:
&quot;app.action::target&quot;.

The third format is used to represent an action with any type of
target value, including strings.  The target value follows the action
name, surrounded in parens.  For example: &quot;app.action(42)&quot;.  The
target value is parsed using g_variant_parse().  If a tuple-typed
value is desired, it must be specified in the same way, resulting in
two sets of parens, for example: &quot;app.action((1,2,3))&quot;.  A string
target can be specified this way as well: &quot;app.action('target')&quot;.
For strings, this third format must be used if * target value is
empty or contains characters other than alphanumerics, '-' and '.'.

Launches the application. Passes @files to the launched application

To launch the application without arguments pass a %NULL @files list.

Note that even if the launch is successful the application launched
can fail to start if it runs into problems during startup. There is
no way to detect this.

Some URIs can be changed when passed through a GFile (for instance
unsupported URIs with strange formats like mailto:), so if you have
a textual URI you want to pass in as argument, consider using
g_app_info_launch_uris() instead.

The launched application inherits the environment of the launching
process, but it can be modified with g_app_launch_context_setenv()
and g_app_launch_context_unsetenv().

On UNIX, this function sets the `GIO_LAUNCHED_DESKTOP_FILE`
environment variable with the path of the launched desktop file and
`GIO_LAUNCHED_DESKTOP_FILE_PID` to the process id of the launched
process. This can be used to ignore `GIO_LAUNCHED_DESKTOP_FILE`,
should it be inherited by further processes. The `DISPLAY` and
`DESKTOP_STARTUP_ID` environment variables are also set, based
on information provided in @context.

<function name="g_application_add_main_option_entries">
<description>
Adds main option entries to be handled by @application.

This function is comparable to g_option_context_add_main_entries().

After the commandline arguments are parsed, the
#GApplication::handle-local-options signal will be emitted.  At this
point, the application can inspect the values pointed to by @arg_data
in the given #GOptionEntrys.

Unlike #GOptionContext, #GApplication supports giving a %NULL
@arg_data for a non-callback #GOptionEntry.  This results in the
argument in question being packed into a #GVariantDict which is also
passed to #GApplication::handle-local-options, where it can be
inspected and modified.  If %G_APPLICATION_HANDLES_COMMAND_LINE is
set, then the resulting dictionary is sent to the primary instance,
where g_application_command_line_get_options_dict() will return it.
This &quot;packing&quot; is done according to the type of the argument --
booleans for normal flags, strings for strings, bytestrings for
filenames, etc.  The packing only occurs if the flag is given (ie: we
do not pack a &quot;false&quot; #GVariant in the case that a flag is missing).

In general, it is recommended that all commandline arguments are
parsed locally.  The options dictionary should then be used to
transmit the result of the parsing to the primary instance, where
g_variant_dict_lookup() can be used.  For local options, it is
possible to either use @arg_data in the usual way, or to consult (and
potentially remove) the option from the options dictionary.

This function is new in GLib 2.40.  Before then, the only real choice
was to send all of the commandline arguments (options and all) to the
primary instance for handling.  #GApplication ignored them completely
on the local side.  Calling this function &quot;opts in&quot; to the new
behaviour, and in particular, means that unrecognised options will be
treated as errors.  Unrecognised options have never been ignored when
%G_APPLICATION_HANDLES_COMMAND_LINE is unset.

If #GApplication::handle-local-options needs to see the list of
filenames, then the use of %G_OPTION_REMAINING is recommended.  If
@arg_data is %NULL then %G_OPTION_REMAINING can be used as a key into
the options dictionary.  If you do use %G_OPTION_REMAINING then you
need to handle these arguments for yourself because once they are
consumed, they will no longer be visible to the default handling
(which treats them as filenames to be opened).

It is important to use the proper GVariant format when retrieving
the options with g_variant_dict_lookup():
- for %G_OPTION_ARG_NONE, use `b`
- for %G_OPTION_ARG_STRING, use `&amp;s`
- for %G_OPTION_ARG_INT, use `i`
- for %G_OPTION_ARG_INT64, use `x`
- for %G_OPTION_ARG_DOUBLE, use `d`
- for %G_OPTION_ARG_FILENAME, use `^&amp;ay`
- for %G_OPTION_ARG_STRING_ARRAY, use `^a&amp;s`
- for %G_OPTION_ARG_FILENAME_ARRAY, use `^a&amp;ay`

<function name="g_application_add_option_group">
<description>
Adds a #GOptionGroup to the commandline handling of @application.

This function is comparable to g_option_context_add_group().

Unlike g_application_add_main_option_entries(), this function does
not deal with %NULL @arg_data and never transmits options to the
primary instance.

The reason for that is because, by the time the options arrive at the
primary instance, it is typically too late to do anything with them.
Taking the GTK option group as an example: GTK will already have been
initialised by the time the #GApplication::command-line handler runs.
In the case that this is not the first-running instance of the
application, the existing instance may already have been running for
a very long time.

This means that the options from #GOptionGroup are only really usable
in the case that the instance of the application being run is the
first instance.  Passing options like `--display=` or `--gdk-debug=`
on future runs will have no effect on the existing primary instance.

Calling this function will cause the options in the supplied option
group to be parsed, but it does not cause you to be &quot;opted in&quot; to the
new functionality whereby unrecognised options are rejected even if
%G_APPLICATION_HANDLES_COMMAND_LINE was given.

<description>
Sets the exit status that will be used when the invoking process

The return value of the #GApplication::command-line signal is
passed to this function when the handler returns.  This is the usual
way of setting the exit status.

In the event that you want the remote invocation to continue running
and want to decide on the exit status in the future, you can use this
call.  For the case of a remote invocation, the remote process will
typically exit when the last reference is dropped on @cmdline.  The
exit status of the remote process will be equal to the last value
that was set with this function.

In the case that the commandline invocation is local, the situation
is slightly more complicated.  If the commandline invocation results
in the mainloop running (ie: because the use-count of the application
increased to a non-zero value) then the application is considered to
have been 'successful' in a certain sense, and the exit status is
always zero.  If the application use count is zero, though, the exit
status of the local #GApplicationCommandLine is used.

<function name="g_application_id_is_valid">
<description>
Checks if @application_id is a valid application identifier.

A valid ID is required for calls to g_application_new() and
g_application_set_application_id().

Application identifiers follow the same format as
[D-Bus well-known bus names](https://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-names-bus).
For convenience, the restrictions on application identifiers are
reproduced here:

- Application identifiers are composed of 1 or more elements separated by a
period (`.`) character. All elements must contain at least one character.

- Each element must only contain the ASCII characters `[A-Z][a-z][0-9]_-`,
with `-` discouraged in new application identifiers. Each element must not
begin with a digit.

- Application identifiers must contain at least one `.` (period) character
(and thus at least two elements).

- Application identifiers must not begin with a `.` (period) character.

- Application identifiers must not exceed 255 characters.

Note that the hyphen (`-`) character is allowed in application identifiers,
but is problematic or not allowed in various specifications and APIs that
refer to D-Bus, such as
[Flatpak application IDs](http://docs.flatpak.org/en/latest/introduction.html#identifiers),
the
[`DBusActivatable` interface in the Desktop Entry Specification](https://specifications.freedesktop.org/desktop-entry-spec/desktop-entry-spec-latest.html#dbus),
and the convention that an application's &quot;main&quot; interface and object path
resemble its application identifier and bus name. To avoid situations that
require special-case handling, it is recommended that new application
identifiers consistently replace hyphens with underscores.

Like D-Bus interface names, application identifiers should start with the
reversed DNS domain name of the author of the interface (in lower-case), and
it is conventional for the rest of the application identifier to consist of
words run together, with initial capital letters.

As with D-Bus interface names, if the author's DNS domain name contains
hyphen/minus characters they should be replaced by underscores, and if it
contains leading digits they should be escaped by prepending an underscore.
For example, if the owner of 7-zip.org used an application identifier for an
archiving application, it might be named `org._7_zip.Archiver`.

<function name="g_application_register">
<description>
Attempts registration of the application.

This is the point at which the application discovers if it is the
primary instance or merely acting as a remote for an already-existing
primary instance.  This is implemented by attempting to acquire the
application identifier as a unique bus name on the session bus using
GDBus.

If there is no application ID or if %G_APPLICATION_NON_UNIQUE was
given, then this process will always become the primary instance.

Due to the internal architecture of GDBus, method calls can be
dispatched at any time (even if a main loop is not running).  For
this reason, you must ensure that any object paths that you wish to
register are registered before calling this function.

If the application has already been registered then %TRUE is
returned with no work performed.

The #GApplication::startup signal is emitted if registration succeeds
and @application is the primary instance (including the non-unique
case).

In the event of an error (such as @cancellable being cancelled, or a
failure to connect to the session bus), %FALSE is returned and @error
is set appropriately.

Note: the return value of this function is not an indicator that this
instance is or is not the primary instance of the application.  See
g_application_get_is_remote() for that.

<function name="g_application_run">
<description>
Runs the application.

This function is intended to be run from main() and its return value
is intended to be returned by main(). Although you are expected to pass
the @argc, @argv parameters from main() to this function, it is possible
to pass %NULL if @argv is not available or commandline handling is not
required.  Note that on Windows, @argc and @argv are ignored, and
g_win32_get_command_line() is called internally (for proper support
of Unicode commandline arguments).

#GApplication will attempt to parse the commandline arguments.  You
can add commandline flags to the list of recognised options by way of
g_application_add_main_option_entries().  After this, the
#GApplication::handle-local-options signal is emitted, from which the
application can inspect the values of its #GOptionEntrys.

#GApplication::handle-local-options is a good place to handle options
such as `--version`, where an immediate reply from the local process is
desired (instead of communicating with an already-running instance).
A #GApplication::handle-local-options handler can stop further processing
by returning a non-negative value, which then becomes the exit status of
the process.

What happens next depends on the flags: if
%G_APPLICATION_HANDLES_COMMAND_LINE was specified then the remaining
commandline arguments are sent to the primary instance, where a
#GApplication::command-line signal is emitted.  Otherwise, the
remaining commandline arguments are assumed to be a list of files.
If there are no files listed, the application is activated via the
#GApplication::activate signal.  If there are one or more files, and
%G_APPLICATION_HANDLES_OPEN was specified then the files are opened
via the #GApplication::open signal.

If you are interested in doing more complicated local handling of the
commandline then you should implement your own #GApplication subclass
and override local_command_line(). In this case, you most likely want
to return %TRUE from your local_command_line() implementation to
suppress the default handling. See
[gapplication-example-cmdline2.c][https://gitlab.gnome.org/GNOME/glib/-/blob/HEAD/gio/tests/gapplication-example-cmdline2.c]
for an example.

If, after the above is done, the use count of the application is zero
then the exit status is returned immediately.  If the use count is
non-zero then the default main context is iterated until the use count
falls to zero, at which point 0 is returned.

If the %G_APPLICATION_IS_SERVICE flag is set, then the service will
run for as much as 10 seconds with a use count of zero while waiting
for the message that caused the activation to arrive.  After that,
if the use count falls to zero the application will exit immediately,
except in the case that g_application_set_inactivity_timeout() is in
use.

This function sets the prgname (g_set_prgname()), if not already set,
to the basename of argv[0].

Much like g_main_loop_run(), this function will acquire the main context
for the duration that the application is running.

Since 2.40, applications that are not explicitly flagged as services
or launchers (ie: neither %G_APPLICATION_IS_SERVICE or
%G_APPLICATION_IS_LAUNCHER are given as flags) will check (from the
default handler for local_command_line) if &quot;--gapplication-service&quot;
was given in the command line.  If this flag is present then normal
commandline processing is interrupted and the
%G_APPLICATION_IS_SERVICE flag is set.  This provides a &quot;compromise&quot;
solution whereby running an application directly from the commandline
will invoke it in the normal way (which can be useful for debugging)
while still allowing applications to be D-Bus activated in service
mode.  The D-Bus service file should invoke the executable with
&quot;--gapplication-service&quot; as the sole commandline argument.  This
approach is suitable for use by most graphical applications but
should not be used from applications like editors that need precise
control over when processes invoked via the commandline will exit and
what their exit status will be.

Sends a notification on behalf of @application to the desktop shell.
There is no guarantee that the notification is displayed immediately,

Notifications may persist after the application exits. It will be

Modifying @notification after this call has no effect. However, the

@id may be any string that uniquely identifies the event for the
application. It does not need to be in any special format. For
example, &quot;new-message&quot; might be appropriate for a notification about
new messages.

If a previous notification was sent with the same @id, it will be
replaced with @notification and shown again as if it was a new
notification. This works even for notifications sent from a previous
execution of the application, as long as @id is the same string.

@id may be %NULL, but it is impossible to replace or withdraw
notifications without an id.

If @notification is no longer relevant, it can be withdrawn with
g_application_withdraw_notification().

Sets (or unsets) the base resource path of @application.

The path is used to automatically load various [application

The various types of resources will be found at fixed names relative
to the given base path.

By default, the resource base path is determined from the application
ID by prefixing '/' and replacing each '.' with '/'.  This is done at
the time that the #GApplication object is constructed.  Changes to
the application ID after that point will not have an impact on the
resource base path.

As an example, if the application has an ID of &quot;org.example.app&quot; then
the default resource base path will be &quot;/org/example/app&quot;.  If this
is a #GtkApplication (and you have not manually changed the path)
then Gtk will then search for the menus of the application at
&quot;/org/example/app/gtk/menus.ui&quot;.

See #GResource for more information about adding resources to your
application.

You can disable automatic resource loading functionality by setting
the path to %NULL.

Changing the resource base path once the application is running is
not recommended.  The point at which the resource path is consulted
for forming paths for various purposes is unspecified.  When writing
a sub-class of #GApplication you should either set the

<function name="g_async_initable_init_async">
<description>
Starts asynchronous initialization of the object implementing the
interface. This must be done before any real use of the object after
initial construction. If the object also implements #GInitable you can
optionally call g_initable_init() instead.

This method is intended for language bindings. If writing in C,
g_async_initable_new_async() should typically be used instead.

When the initialization is finished, @callback will be called. You can
then call g_async_initable_init_finish() to get the result of the
initialization.

Implementations may also support cancellation. If @cancellable is not
%NULL, then initialization can be cancelled by triggering the cancellable
object from another thread. If the operation was cancelled, the error
%G_IO_ERROR_CANCELLED will be returned. If @cancellable is not %NULL, and
the object doesn't support cancellable initialization, the error
%G_IO_ERROR_NOT_SUPPORTED will be returned.

As with #GInitable, if the object is not initialized, or initialization
returns with an error, then all operations on the object except
g_object_ref() and g_object_unref() are considered to be invalid, and
have undefined behaviour. They will often fail with g_critical() or
g_warning(), but this must not be relied on.

Callers should not assume that a class which implements #GAsyncInitable can
be initialized multiple times; for more information, see g_initable_init().
If a class explicitly supports being initialized multiple times,
implementation requires yielding all subsequent calls to init_async() on the
results of the first call.

For classes that also support the #GInitable interface, the default
implementation of this method will run the g_initable_init() function
in a thread, so if you want to support asynchronous initialization via
threads, just implement the #GAsyncInitable interface without overriding
any interface methods.

<function name="g_buffered_input_stream_fill">
<description>
Tries to read @count bytes from the stream into the buffer.
Will block during this read.

If @count is zero, returns zero and does nothing. A value of @count
larger than %G_MAXSSIZE will cause a %G_IO_ERROR_INVALID_ARGUMENT error.

On success, the number of bytes read into the buffer is returned.
It is not an error if this is not the same as the requested size, as it
can happen e.g. near the end of a file. Zero is returned on end of file
(or if @count is zero),  but never otherwise.

If @count is -1 then the attempted read size is equal to the number of
bytes that are required to fill the buffer.

If @cancellable is not %NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error %G_IO_ERROR_CANCELLED will be returned. If an
operation was partially finished when the operation was cancelled the
partial result will be returned, without an error.

On error -1 is returned and @error is set accordingly.

<function name="g_bus_own_name">
<description>
Starts acquiring @name on the bus specified by @bus_type and calls
@name_acquired_handler and @name_lost_handler when the name is
acquired respectively lost. Callbacks will be invoked in the 
[thread-default main context][g-main-context-push-thread-default]
of the thread you are calling this function from.

You are guaranteed that one of the @name_acquired_handler and @name_lost_handler
callbacks will be invoked after calling this function - there are three
possible cases:

- @name_lost_handler with a %NULL connection (if a connection to the bus
can't be made).

- @bus_acquired_handler then @name_lost_handler (if the name can't be
obtained)

- @bus_acquired_handler then @name_acquired_handler (if the name was
obtained).

When you are done owning the name, just call g_bus_unown_name()
with the owner id this function returns.

If the name is acquired or lost (for example another application
could acquire the name if you allow replacement or the application
currently owning the name exits), the handlers are also invoked.
If the #GDBusConnection that is used for attempting to own the name
closes, then @name_lost_handler is invoked since it is no longer
possible for other processes to access the process.

You cannot use g_bus_own_name() several times for the same name (unless
interleaved with calls to g_bus_unown_name()) - only the first call
will work.

Another guarantee is that invocations of @name_acquired_handler
and @name_lost_handler are guaranteed to alternate; that
is, if @name_acquired_handler is invoked then you are
guaranteed that the next time one of the handlers is invoked, it
will be @name_lost_handler. The reverse is also true.

If you plan on exporting objects (using e.g.
g_dbus_connection_register_object()), note that it is generally too late
to export the objects in @name_acquired_handler. Instead, you can do this
in @bus_acquired_handler since you are guaranteed that this will run
before @name is requested from the bus.

This behavior makes it very simple to write applications that wants
to [own names][gdbus-owning-names] and export objects.
Simply register objects to be exported in @bus_acquired_handler and
unregister the objects (if any) in @name_lost_handler.

<function name="g_bus_watch_name">
<description>
Starts watching @name on the bus specified by @bus_type and calls
@name_appeared_handler and @name_vanished_handler when the name is
known to have an owner respectively known to lose its
owner. Callbacks will be invoked in the
[thread-default main context][g-main-context-push-thread-default]
of the thread you are calling this function from.

You are guaranteed that one of the handlers will be invoked after
calling this function. When you are done watching the name, just
call g_bus_unwatch_name() with the watcher id this function
returns.

If the name vanishes or appears (for example the application owning
the name could restart), the handlers are also invoked. If the
#GDBusConnection that is used for watching the name disconnects, then
@name_vanished_handler is invoked since it is no longer
possible to access the name.

Another guarantee is that invocations of @name_appeared_handler
and @name_vanished_handler are guaranteed to alternate; that
is, if @name_appeared_handler is invoked then you are
guaranteed that the next time one of the handlers is invoked, it
will be @name_vanished_handler. The reverse is also true.

This behavior makes it very simple to write applications that want
to take action when a certain [name exists][gdbus-watching-names].
Basically, the application should create object proxies in
@name_appeared_handler and destroy them again (if any) in
@name_vanished_handler.

<description>
Will set @cancellable to cancelled, and will emit the

race conditions in the documentation for that signal if you are
planning to connect to it.)

This function is thread-safe. In other words, you can safely call
it from a thread other than the one running the operation that was
passed the @cancellable.

If @cancellable is %NULL, this function returns immediately for convenience.

The convention within GIO is that cancelling an asynchronous
operation causes it to complete asynchronously. That is, if you
cancel the operation from the same thread in which it is running,
then the operation's #GAsyncReadyCallback will not be invoked until
the application returns to the main loop.

<function name="g_cancellable_connect">
<description>
Convenience function to connect to the #GCancellable::cancelled
signal. Also handles the race condition that may happen
if the cancellable is cancelled right before connecting.

@callback is called at most once, either directly at the
time of the connect if @cancellable is already cancelled,
or when @cancellable is cancelled in some thread.

@data_destroy_func will be called when the handler is
disconnected, or immediately if the cancellable is already
cancelled.

See #GCancellable::cancelled for details on how to use this.

Since GLib 2.40, the lock protecting @cancellable is not held when
@callback is invoked.  This lifts a restriction in place for
earlier GLib versions which now makes it easier to write cleanup
code that unconditionally invokes e.g. g_cancellable_cancel().

<function name="g_cancellable_disconnect">
<description>
Disconnects a handler from a cancellable instance similar to
g_signal_handler_disconnect().  Additionally, in the event that a
signal handler is currently running, this call will block until the
handler has finished.  Calling this function from a
#GCancellable::cancelled signal handler will therefore result in a
deadlock.

This avoids a race condition where a thread cancels at the
same time as the cancellable operation is finished and the
signal handler is removed. See #GCancellable::cancelled for
details on how to use this.

If @cancellable is %NULL or @handler_id is `0` this function does
nothing.

Gets the file descriptor for a cancellable job. This can be used to

You are not supposed to read from the fd yourself, just check for
readable status. Reading to unset the readable status is done
with g_cancellable_reset().

<description>
Creates a #GPollFD corresponding to @cancellable; this can be passed
to g_poll() and used to poll for cancellation. This is useful both
for unix systems without a native poll and for portability to
windows.

When this function returns %TRUE, you should use 
g_cancellable_release_fd() to free up resources allocated for the 
@pollfd. After a %FALSE return, do not call g_cancellable_release_fd().

If this function returns %FALSE, either no @cancellable was given or
resource limits prevent this function from allocating the necessary 
structures for polling. (On Linux, you will likely have reached 
the maximum number of file descriptors.) The suggested way to handle
these cases is to ignore the @cancellable.

You are not supposed to read from the fd yourself, just check for
readable status. Reading to unset the readable status is done
with g_cancellable_reset().

Note that it is generally not a good idea to reuse an existing
cancellable for more operations after it has been cancelled once,
as this function might tempt you to do. The recommended practice
is to drop the reference to a cancellable after cancelling it,
and let it die with the outstanding async operations. You should

Set the list of directories used by GIO to load the MIME database.
If @dirs is %NULL, the directories used are the default:

- the `mime` subdirectory of every directory in `$XDG_DATA_DIRS`

This function is intended to be used when writing tests that depend on
information stored in the MIME database, in order to control the data.

Typically, in case your tests use %G_TEST_OPTION_ISOLATE_DIRS, but they
depend on the system’s MIME database, you should call this function
with @dirs set to %NULL before calling g_test_init(), for instance:

|[&lt;!-- language=&quot;C&quot; --&gt;
// Load MIME data from the system
g_content_type_set_mime_dirs (NULL);
// Isolate the environment
g_test_init (&amp;argc, &amp;argv, G_TEST_OPTION_ISOLATE_DIRS, NULL);

…

<function name="g_converter_convert">
<description>
This is the main operation used when converting data. It is to be called
multiple times in a loop, and each time it will do some work, i.e.
producing some output (in @outbuf) or consuming some input (from @inbuf) or
both. If its not possible to do any work an error is returned.

Note that a single call may not consume all input (or any input at all).
Also a call may produce output even if given no input, due to state stored
in the converter producing output.

If any data was either produced or consumed, and then an error happens, then
only the successful conversion is reported and the error is returned on the
next call.

A full conversion loop involves calling this method repeatedly, each time
giving it new input and space output space. When there is no more input
data after the data in @inbuf, the flag %G_CONVERTER_INPUT_AT_END must be set.
The loop will be (unless some error happens) returning %G_CONVERTER_CONVERTED
each time until all data is consumed and all output is produced, then
%G_CONVERTER_FINISHED is returned instead. Note, that %G_CONVERTER_FINISHED
may be returned even if %G_CONVERTER_INPUT_AT_END is not set, for instance
in a decompression converter where the end of data is detectable from the
data (and there might even be other data after the end of the compressed data).

When some data has successfully been converted @bytes_read and is set to
the number of bytes read from @inbuf, and @bytes_written is set to indicate
how many bytes was written to @outbuf. If there are more data to output
or consume (i.e. unless the %G_CONVERTER_INPUT_AT_END is specified) then
%G_CONVERTER_CONVERTED is returned, and if no more data is to be output
then %G_CONVERTER_FINISHED is returned.

On error %G_CONVERTER_ERROR is returned and @error is set accordingly.
Some errors need special handling:

%G_IO_ERROR_NO_SPACE is returned if there is not enough space
to write the resulting converted data, the application should
call the function again with a larger @outbuf to continue.

%G_IO_ERROR_PARTIAL_INPUT is returned if there is not enough
input to fully determine what the conversion should produce,
and the %G_CONVERTER_INPUT_AT_END flag is not set. This happens for
example with an incomplete multibyte sequence when converting text,
or when a regexp matches up to the end of the input (and may match
further input). It may also happen when @inbuf_size is zero and
there is no more data to produce.

When this happens the application should read more input and then
call the function again. If further input shows that there is no
more data call the function again with the same data but with
the %G_CONVERTER_INPUT_AT_END flag set. This may cause the conversion
to finish as e.g. in the regexp match case (or, to fail again with
%G_IO_ERROR_PARTIAL_INPUT in e.g. a charset conversion where the
input is actually partial).

After g_converter_convert() has returned %G_CONVERTER_FINISHED the
converter object is in an invalid state where its not allowed
to call g_converter_convert() anymore. At this time you can only
free the object or call g_converter_reset() to reset it to the
initial state.

If the flag %G_CONVERTER_FLUSH is set then conversion is modified
to try to write out all internal state to the output. The application
has to call the function multiple times with the flag set, and when
the available input has been consumed and all internal state has
been produced then %G_CONVERTER_FLUSHED (or %G_CONVERTER_FINISHED if
really at the end) is returned instead of %G_CONVERTER_CONVERTED.
This is somewhat similar to what happens at the end of the input stream,
but done in the middle of the data.

This has different meanings for different conversions. For instance
in a compression converter it would mean that we flush all the
compression state into output such that if you uncompress the
compressed data you get back all the input data. Doing this may
make the final file larger due to padding though. Another example
is a regexp conversion, where if you at the end of the flushed data
have a match, but there is also a potential longer match. In the
non-flushed case we would ask for more input, but when flushing we
treat this as the end of input and do the match.

Flushing is not always possible (like if a charset converter flushes
at a partial multibyte sequence). Converters are supposed to try
to produce as much output as possible and then return an error
(typically %G_IO_ERROR_PARTIAL_INPUT).

<description>
Checks on the readiness of @datagram_based to perform operations. The
operations specified in @condition are checked for and masked against the
currently-satisfied conditions on @datagram_based. The result is returned.

%G_IO_IN will be set in the return value if data is available to read with
g_datagram_based_receive_messages(), or if the connection is closed remotely
(EOS); and if the datagram_based has not been closed locally using some
implementation-specific method (such as g_socket_close() or
g_socket_shutdown() with @shutdown_read set, if it’s a #GSocket).

If the connection is shut down or closed (by calling g_socket_close() or
g_socket_shutdown() with @shutdown_read set, if it’s a #GSocket, for
example), all calls to this function will return %G_IO_ERROR_CLOSED.

%G_IO_OUT will be set if it is expected that at least one byte can be sent
using g_datagram_based_send_messages() without blocking. It will not be set
if the datagram_based has been closed locally.

%G_IO_HUP will be set if the connection has been closed locally.

%G_IO_ERR will be set if there was an asynchronous error in transmitting data
previously enqueued using g_datagram_based_send_messages().

Note that on Windows, it is possible for an operation to return
%G_IO_ERROR_WOULD_BLOCK even immediately after
g_datagram_based_condition_check() has claimed that the #GDatagramBased is
ready for writing. Rather than calling g_datagram_based_condition_check() and
then writing to the #GDatagramBased if it succeeds, it is generally better to
simply try writing right away, and try again later if the initial attempt
returns %G_IO_ERROR_WOULD_BLOCK.

It is meaningless to specify %G_IO_ERR or %G_IO_HUP in @condition; these
conditions will always be set in the output if they are true. Apart from
these flags, the output is guaranteed to be masked by @condition.

This call never blocks.

If non-%NULL, @cancellable can be used to cancel the source, which will
cause the source to trigger, reporting the current condition (which is

change). You can check for this in the callback using
g_cancellable_is_cancelled().

<function name="g_datagram_based_receive_messages">
<description>
Receive one or more data messages from @datagram_based in one go.

@messages must point to an array of #GInputMessage structs and
@num_messages must be the length of this array. Each #GInputMessage
contains a pointer to an array of #GInputVector structs describing the
buffers that the data received in each message will be written to.

@flags modify how all messages are received. The commonly available
arguments for this are available in the #GSocketMsgFlags enum, but the
values there are the same as the system values, and the flags
are passed in as-is, so you can pass in system-specific flags too. These
flags affect the overall receive operation. Flags affecting individual
messages are returned in #GInputMessage.flags.

The other members of #GInputMessage are treated as described in its
documentation.

If @timeout is negative the call will block until @num_messages have been
received, the connection is closed remotely (EOS), @cancellable is cancelled,
or an error occurs.

If @timeout is 0 the call will return up to @num_messages without blocking,
or %G_IO_ERROR_WOULD_BLOCK if no messages are queued in the operating system
to be received.

If @timeout is positive the call will block on the same conditions as if
@timeout were negative. If the timeout is reached
before any messages are received, %G_IO_ERROR_TIMED_OUT is returned,
otherwise it will return the number of messages received before timing out.
(Note: This is effectively the behaviour of `MSG_WAITFORONE` with
recvmmsg().)

To be notified when messages are available, wait for the %G_IO_IN condition.
Note though that you may still receive %G_IO_ERROR_WOULD_BLOCK from
g_datagram_based_receive_messages() even if you were previously notified of a
%G_IO_IN condition.

If the remote peer closes the connection, any messages queued in the
underlying receive buffer will be returned, and subsequent calls to
g_datagram_based_receive_messages() will return 0 (with no error set).

If the connection is shut down or closed (by calling g_socket_close() or
g_socket_shutdown() with @shutdown_read set, if it’s a #GSocket, for
example), all calls to this function will return %G_IO_ERROR_CLOSED.

On error -1 is returned and @error is set accordingly. An error will only
be returned if zero messages could be received; otherwise the number of
messages successfully received before the error will be returned. If
@cancellable is cancelled, %G_IO_ERROR_CANCELLED is returned as with any
other error.

for this are available in the #GSocketMsgFlags enum, but the
values there are the same as the system values, and the flags
are passed in as-is, so you can pass in system-specific flags too.

The other members of #GOutputMessage are treated as described in its
documentation.

If @timeout is negative the call will block until @num_messages have been
sent, @cancellable is cancelled, or an error occurs.

If @timeout is 0 the call will send up to @num_messages without blocking,
or will return %G_IO_ERROR_WOULD_BLOCK if there is no space to send messages.

If @timeout is positive the call will block on the same conditions as if
@timeout were negative. If the timeout is reached before any messages are
sent, %G_IO_ERROR_TIMED_OUT is returned, otherwise it will return the number
of messages sent before timing out.

To be notified when messages can be sent, wait for the %G_IO_OUT condition.
Note though that you may still receive %G_IO_ERROR_WOULD_BLOCK from
g_datagram_based_send_messages() even if you were previously notified of a
%G_IO_OUT condition. (On Windows in particular, this is very common due to
the way the underlying APIs work.)

If the connection is shut down or closed (by calling g_socket_close() or
g_socket_shutdown() with @shutdown_write set, if it’s a #GSocket, for
example), all calls to this function will return %G_IO_ERROR_CLOSED.

On error -1 is returned and @error is set accordingly. An error will only
be returned if zero messages could be sent; otherwise the number of messages
successfully sent before the error will be returned. If @cancellable is
cancelled, %G_IO_ERROR_CANCELLED is returned as with any other error.

<function name="g_dbus_action_group_get">
<description>
Obtains a #GDBusActionGroup for the action group which is exported at
the given @bus_name and @object_path.

The thread default main context is taken at the time of this call.
All signals on the menu model (and any linked models) are reported
with respect to this context.  All calls on the returned menu model
(and linked models) must also originate from this same context, with
the thread default main context unchanged.

This call is non-blocking.  The returned action group may or may not
already be filled in.  The correct thing to do is connect the signals
for the action group to monitor for changes and then to call
g_action_group_list_actions() to get the initial list.

<function name="g_dbus_connection_add_filter">
<description>
Adds a message filter. Filters are handlers that are run on all
incoming and outgoing messages, prior to standard dispatch. Filters
are run in the order that they were added.  The same handler can be
added as a filter more than once, in which case it will be run more
than once.  Filters added during a filter callback won't be run on
the message being processed. Filter functions are allowed to modify
and even drop messages.

Note that filters are run in a dedicated message handling thread so
they can't block and, generally, can't do anything but signal a
worker thread. Also note that filters are rarely needed - use API
such as g_dbus_connection_send_message_with_reply(),
g_dbus_connection_signal_subscribe() or g_dbus_connection_call() instead.

If a filter consumes an incoming message the message is not
dispatched anywhere else - not even the standard dispatch machinery
(that API such as g_dbus_connection_signal_subscribe() and
g_dbus_connection_send_message_with_reply() relies on) will see the
message. Similarly, if a filter consumes an outgoing message, the
message will not be sent to the other peer.

If @user_data_free_func is non-%NULL, it will be called (in the
thread-default main context of the thread you are calling this
method from) at some point after @user_data is no longer
needed. (It is not guaranteed to be called synchronously when the
filter is removed, and may be called after @connection has been
destroyed.)

<function name="g_dbus_connection_close">
<description>
Closes @connection. Note that this never causes the process to
exit (this might only happen if the other end of a shared message
bus connection disconnects, see #GDBusConnection:exit-on-close).

Once the connection is closed, operations such as sending a message
will return with the error %G_IO_ERROR_CLOSED. Closing a connection
will not automatically flush the connection so queued messages may
be lost. Use g_dbus_connection_flush() if you need such guarantees.

If @connection is already closed, this method fails with
%G_IO_ERROR_CLOSED.

When @connection has been closed, the #GDBusConnection::closed
signal is emitted in the
[thread-default main context][g-main-context-push-thread-default]
of the thread that @connection was constructed in.

This is an asynchronous method. When the operation is finished,
@callback will be invoked in the 
[thread-default main context][g-main-context-push-thread-default]
of the thread you are calling this method from. You can
then call g_dbus_connection_close_finish() to get the result of the
operation. See g_dbus_connection_close_sync() for the synchronous

The thread default main context is taken at the time of this call.
All incoming action activations and state change requests are
reported from this context.  Any changes on the action group that
cause it to emit signals must also come from this same context.
Since incoming action activations and state change requests are
rather likely to cause changes on the action group, this effectively
limits a given action group to being exported from only one main

<description>
Registers callbacks for exported objects at @object_path with the
D-Bus interface that is described in @interface_info.

Calls to functions in @vtable (and @user_data_free_func) will happen
in the 
[thread-default main context][g-main-context-push-thread-default]
of the thread you are calling this method from.

Note that all #GVariant values passed to functions in @vtable will match
the signature given in @interface_info - if a remote caller passes
incorrect values, the `org.freedesktop.DBus.Error.InvalidArgs`
is returned to the remote caller.

Additionally, if the remote caller attempts to invoke methods or
access properties not mentioned in @interface_info the
`org.freedesktop.DBus.Error.UnknownMethod` resp.
`org.freedesktop.DBus.Error.InvalidArgs` errors
are returned to the caller.

It is considered a programming error if the
#GDBusInterfaceGetPropertyFunc function in @vtable returns a
#GVariant of incorrect type.

If an existing callback is already registered at @object_path and
@interface_name, then @error is set to %G_IO_ERROR_EXISTS.

GDBus automatically implements the standard D-Bus interfaces
org.freedesktop.DBus.Properties, org.freedesktop.DBus.Introspectable
and org.freedesktop.Peer, so you don't have to implement those for the
objects you export. You can implement org.freedesktop.DBus.Properties
yourself, e.g. to handle getting and setting of properties asynchronously.

Note that the reference count on @interface_info will be
incremented by 1 (unless allocated statically, e.g. if the
reference count is -1, see g_dbus_interface_info_ref()) for as long
as the object is exported. Also note that @vtable will be copied.

See this [server][gdbus-server] for an example of how to use this method.

<function name="g_dbus_connection_register_subtree">
<description>
Registers a whole subtree of dynamic objects.

The @enumerate and @introspection functions in @vtable are used to
convey, to remote callers, what nodes exist in the subtree rooted
by @object_path.

When handling remote calls into any node in the subtree, first the
@enumerate function is used to check if the node exists. If the node exists
or the %G_DBUS_SUBTREE_FLAGS_DISPATCH_TO_UNENUMERATED_NODES flag is set
the @introspection function is used to check if the node supports the
requested method. If so, the @dispatch function is used to determine
where to dispatch the call. The collected #GDBusInterfaceVTable and
#gpointer will be used to call into the interface vtable for processing
the request.

All calls into user-provided code will be invoked in the
[thread-default main context][g-main-context-push-thread-default]
of the thread you are calling this method from.

If an existing subtree is already registered at @object_path or
then @error is set to %G_IO_ERROR_EXISTS.

Note that it is valid to register regular objects (using
g_dbus_connection_register_object()) in a subtree registered with
g_dbus_connection_register_subtree() - if so, the subtree handler
is tried as the last resort. One way to think about a subtree
handler is to consider it a fallback handler for object paths not
registered via g_dbus_connection_register_object() or other bindings.

Note that @vtable will be copied so you cannot change it after
registration.

See this [server][gdbus-subtree-server] for an example of how to use
this method.

<function name="g_dbus_connection_signal_subscribe">
<description>
Subscribes to signals on @connection and invokes @callback with a whenever
the signal is received. Note that @callback will be invoked in the 
[thread-default main context][g-main-context-push-thread-default]
of the thread you are calling this method from.

If @connection is not a message bus connection, @sender must be
%NULL.

If @sender is a well-known name note that @callback is invoked with
the unique name for the owner of @sender, not the well-known name
as one would expect. This is because the message bus rewrites the
name. As such, to avoid certain race conditions, users should be
tracking the name owner of the well-known name and use that when
processing the received signal.

If one of %G_DBUS_SIGNAL_FLAGS_MATCH_ARG0_NAMESPACE or
%G_DBUS_SIGNAL_FLAGS_MATCH_ARG0_PATH are given, @arg0 is
interpreted as part of a namespace or path.  The first argument
of a signal is matched against that part as specified by D-Bus.

If @user_data_free_func is non-%NULL, it will be called (in the
thread-default main context of the thread you are calling this
method from) at some point after @user_data is no longer
needed. (It is not guaranteed to be called synchronously when the
signal is unsubscribed from, and may be called after @connection
has been destroyed.)

As @callback is potentially invoked in a different thread from where it’s
emitted, it’s possible for this to happen after
g_dbus_connection_signal_unsubscribe() has been called in another thread.
Due to this, @user_data should have a strong reference which is freed with
@user_data_free_func, rather than pointing to data whose lifecycle is tied
to the signal subscription. For example, if a #GObject is used to store the
subscription ID from g_dbus_connection_signal_subscribe(), a strong reference
to that #GObject must be passed to @user_data, and g_object_unref() passed to
@user_data_free_func. You are responsible for breaking the resulting
reference count cycle by explicitly unsubscribing from the signal when
dropping the last external reference to the #GObject. Alternatively, a weak
reference may be used.

It is guaranteed that if you unsubscribe from a signal using
g_dbus_connection_signal_unsubscribe() from the same thread which made the
corresponding g_dbus_connection_signal_subscribe() call, @callback will not
be invoked after g_dbus_connection_signal_unsubscribe() returns.

The returned subscription identifier is an opaque value which is guaranteed
to never be zero.

This function can never fail.

<description>
Escapes @bytes for use in a D-Bus object path component.
@bytes is an array of zero or more nonzero bytes in an
unspecified encoding, followed by a single zero byte.

The escaping method consists of replacing all non-alphanumeric
characters (see g_ascii_isalnum()) with their hexadecimal value
preceded by an underscore (`_`). For example:
`foo.bar.baz` will become `foo_2ebar_2ebaz`.

This method is appropriate to use when the input is nearly
a valid object path component but is not when your input
is far from being a valid object path component.
Other escaping algorithms are also valid to use with
D-Bus object paths.

This can be reversed with g_dbus_unescape_object_path().

<function name="g_dbus_gvalue_to_gvariant">
<description>
Converts a #GValue to a #GVariant of the type indicated by the @type
parameter.

The conversion is using the following rules:

- `G_TYPE_STRING`: 's', 'o', 'g' or 'ay'
- `G_TYPE_STRV`: 'as', 'ao' or 'aay'
- `G_TYPE_BOOLEAN`: 'b'
- `G_TYPE_UCHAR`: 'y'
- `G_TYPE_INT`: 'i', 'n'
- `G_TYPE_UINT`: 'u', 'q'
- `G_TYPE_INT64`: 'x'
- `G_TYPE_UINT64`: 't'
- `G_TYPE_DOUBLE`: 'd'
- `G_TYPE_VARIANT`: Any #GVariantType

This can fail if e.g. @gvalue is of type %G_TYPE_STRING and @type
is 'i', i.e. %G_VARIANT_TYPE_INT32. It will also fail for any #GType
(including e.g. %G_TYPE_OBJECT and %G_TYPE_BOXED derived-types) not
in the table above.

Note that if @gvalue is of type %G_TYPE_VARIANT and its value is
%NULL, the empty #GVariant instance (never %NULL) for @type is
returned (e.g. 0 for scalar types, the empty string for string types,
'/' for object path types, the empty array for any array type and so on).

Converts a #GVariant to a #GValue. If @value is floating, it is consumed.

The rules specified in the g_dbus_gvalue_to_gvariant() function are
used - this function is essentially its reverse form. So, a #GVariant
containing any basic or string array type will be converted to a #GValue
containing a basic value or string array. Any other #GVariant (handle,
variant, tuple, dict entry) will be converted to a #GValue containing that
#GVariant.

The conversion never fails - a valid #GValue is always returned in

`org.gtk.GDBus.UnmappedGError.Quark...` is used. This provides
transparent mapping of #GError between applications using GDBus.

<function name="g_dbus_proxy_call">
<description>
Asynchronously invokes the @method_name method on @proxy.

If @method_name contains any dots, then @name is split into interface and
method name parts. This allows using @proxy for invoking methods on
other interfaces.

If the #GDBusConnection associated with @proxy is closed then
the operation will fail with %G_IO_ERROR_CLOSED. If
@cancellable is canceled, the operation will fail with
%G_IO_ERROR_CANCELLED. If @parameters contains a value not
compatible with the D-Bus protocol, the operation fails with
%G_IO_ERROR_INVALID_ARGUMENT.

If the @parameters #GVariant is floating, it is consumed. This allows
convenient 'inline' use of g_variant_new(), e.g.:

If @proxy has an expected interface (see
#GDBusProxy:g-interface-info) and @method_name is referenced by it,
then the return value is checked against the return type.

This is an asynchronous method. When the operation is finished,
@callback will be invoked in the
[thread-default main context][g-main-context-push-thread-default]
of the thread you are calling this method from.
You can then call g_dbus_proxy_call_finish() to get the result of
the operation. See g_dbus_proxy_call_sync() for the synchronous
version of this method.

If @callback is %NULL then the D-Bus method call message will be sent with
the %G_DBUS_MESSAGE_FLAGS_NO_REPLY_EXPECTED flag set.

<description>
If @value is not %NULL, sets the cached value for the property with
name @property_name to the value in @value.

If @value is %NULL, then the cached value is removed from the
property cache.

If @proxy has an expected interface (see
#GDBusProxy:g-interface-info) and @property_name is referenced by
it, then @value is checked against the type of the property.

If the @value #GVariant is floating, it is consumed. This allows
convenient 'inline' use of g_variant_new(), e.g.
|[&lt;!-- language=&quot;C&quot; --&gt;
g_dbus_proxy_set_cached_property (proxy,
&quot;SomeProperty&quot;,
g_variant_new (&quot;(si)&quot;,
&quot;A String&quot;,
42));
]|

Normally you will not need to use this method since @proxy
is tracking changes using the
`org.freedesktop.DBus.Properties.PropertiesChanged`
D-Bus signal. However, for performance reasons an object may
decide to not use this signal for some properties and instead
use a proprietary out-of-band mechanism to transmit changes.

As a concrete example, consider an object with a property
`ChatroomParticipants` which is an array of strings. Instead of
transmitting the same (long) array every time the property changes,
it is more efficient to only transmit the delta using e.g. signals
`ChatroomParticipantJoined(String name)` and
`ChatroomParticipantParted(String name)`.

Activates the named application action.

You may only call this function on action names that were
returned from g_desktop_app_info_list_actions().

Note that if the main entry of the desktop file indicates that the
application supports startup notification, and @launch_context is
non-%NULL, then startup notification will be used when activating the
action (and as such, invocation of the action on the receiving side
must signal the end of startup notification when it is completed).
This is the expected behaviour of applications declaring additional
actions, as per the desktop file specification.

As with g_app_info_launch() there is no way to detect failures that
occur while using this function.

<description>
This function performs the equivalent of g_app_info_launch_uris(),
but is intended primarily for operating system components that
launch applications.  Ordinary applications should use
g_app_info_launch_uris().

If the application is launched via GSpawn, then @spawn_flags, @user_setup
and @user_setup_data are used for the call to g_spawn_async().
Additionally, @pid_callback (with @pid_callback_data) will be called to
inform about the PID of the created process. See g_spawn_async_with_pipes()
for information on certain parameter conditions that can enable an
optimized posix_spawn() codepath to be used.

If application launching occurs via some other mechanism (eg: D-Bus
activation) then @spawn_flags, @user_setup, @user_setup_data,
@pid_callback and @pid_callback_data are ignored.

Creates a new #GDesktopAppInfo based on a desktop file id.

A desktop file id is the basename of the desktop file, including the

in the `applications` subdirectories of the XDG
data directories (i.e. the directories specified in the `XDG_DATA_HOME`
and `XDG_DATA_DIRS` environment variables). GIO also supports the
prefix-to-subdirectory mapping that is described in the
[Menu Spec](http://standards.freedesktop.org/menu-spec/latest/)

`/usr/share/applications/kde/foo.desktop`).

best-matching applications, and so on.
The algorithm for determining matches is undefined and may change at
any time.

None of the search results are subjected to the normal validation
checks performed by g_desktop_app_info_new() (for example, checking that
the executable referenced by a result exists), and so it is possible for
g_desktop_app_info_new() to return %NULL when passed an app ID returned by
this function. It is expected that calling code will do this when
subsequently creating a #GDesktopAppInfo for each result.

Close the DTLS connection. This is equivalent to calling

Closing a #GDtlsConnection waits for all buffered but untransmitted data to

peer and may wait for a `close_notify` to be received from the peer. It does
not close the underlying #GDtlsConnection:base-socket; that must be closed
separately.

Once @conn is closed, all other operations will return %G_IO_ERROR_CLOSED.
Closing a #GDtlsConnection multiple times will not return an error.

#GDtlsConnections will be automatically closed when the last reference is
dropped, but you might want to call this function to make sure resources are

If @cancellable is cancelled, the #GDtlsConnection may be left

<description>
Attempts a TLS handshake on @conn.

On the client side, it is never necessary to call this method;
although the connection needs to perform a handshake after
connecting, #GDtlsConnection will handle this for you automatically
when you try to send or receive data on the connection. You can call
g_dtls_connection_handshake() manually if you want to know whether
the initial handshake succeeded or failed (as opposed to just
immediately trying to use @conn to read or write, in which case,
if it fails, it may not be possible to tell if it failed before
or after completing the handshake), but beware that servers may reject
client authentication after the handshake has completed, so a
successful handshake does not indicate the connection will be usable.

Likewise, on the server side, although a handshake is necessary at
the beginning of the communication, you do not need to call this
function explicitly unless you want clearer error reporting.

Previously, calling g_dtls_connection_handshake() after the initial
handshake would trigger a rehandshake; however, this usage was
deprecated in GLib 2.60 because rehandshaking was removed from the
TLS protocol in TLS 1.3. Since GLib 2.64, calling this function after
the initial handshake will no longer do anything.

This sets the certificate that @conn will present to its peer

For a #GDtlsClientConnection, this is optional. If a handshake fails

requires a certificate, and if you try connecting again, you should
call this method first. You can call
g_dtls_client_connection_get_accepted_cas() on the failed connection
to get a list of Certificate Authorities that the server will
accept certificates from.

(It is also possible that a server will allow the connection with
or without a certificate; in that case, if you don't provide a
certificate, you can tell that the server requested one by the fact
that g_dtls_client_connection_get_accepted_cas() will return

<description>
Sets whether or not @conn expects a proper TLS close notification

peer before the connection is closed, and will return a
%G_TLS_ERROR_EOF error if the connection is closed without proper
notification (since this may indicate a network error, or
man-in-the-middle attack).

In some protocols, the application will know whether or not the
connection was closed cleanly based on application-level data
(because the application-level data includes a length field, or is
somehow self-delimiting); in this case, the close notify is
redundant and may be omitted. You
can use g_dtls_connection_set_require_close_notify() to tell @conn
to allow an &quot;unannounced&quot; connection close, in which case the close
will show up as a 0-length read, as in a non-TLS
#GDatagramBased, and it is up to the application to check that
the data has been fully received.

Note that this only affects the behavior when the peer closes the
connection; when the application calls g_dtls_connection_close_async() on
@conn itself, this will send a close notification regardless of the
setting of this property. If you explicitly want to do an unclean
close, you can close @conn's #GDtlsConnection:base-socket rather
than closing @conn itself.

<function name="g_dtls_connection_shutdown">
<description>
Shut down part or all of a DTLS connection.

If @shutdown_read is %TRUE then the receiving side of the connection is shut
down, and further reading is disallowed. Subsequent calls to
g_datagram_based_receive_messages() will return %G_IO_ERROR_CLOSED.

If @shutdown_write is %TRUE then the sending side of the connection is shut
down, and further writing is disallowed. Subsequent calls to
g_datagram_based_send_messages() will return %G_IO_ERROR_CLOSED.

It is allowed for both @shutdown_read and @shutdown_write to be TRUE — this
is equivalent to calling g_dtls_connection_close().

If @cancellable is cancelled, the #GDtlsConnection may be left
partially-closed and any pending untransmitted data may be lost. Call
g_dtls_connection_shutdown() again to complete closing the #GDtlsConnection.

By default files created are generally readable by everyone,

will be made readable only to the current user, to the level that
is supported on the target filesystem.

If @cancellable is not %NULL, then the operation can be cancelled
by triggering the cancellable object from another thread. If the
operation was cancelled, the error %G_IO_ERROR_CANCELLED will be
returned.

Some file systems don't allow all file names, and may return an
%G_IO_ERROR_INVALID_FILENAME error. If the file is a directory the
%G_IO_ERROR_IS_DIRECTORY error will be returned. Other errors are
possible too, and depend on what kind of filesystem the file is on.

<function name="g_file_attribute_matcher_new">
<description>
Creates a new file attribute matcher, which matches attributes
against a given string. #GFileAttributeMatchers are reference
counted structures, and are created with a reference count of 1. If
the number of references falls to 0, the #GFileAttributeMatcher is
automatically destroyed.

The @attributes string should be formatted with specific keys separated
from namespaces with a double colon. Several &quot;namespace::key&quot; strings may be
concatenated with a single comma (e.g. &quot;standard::type,standard::is-hidden&quot;).
The wildcard &quot;*&quot; may be used to match all keys and namespaces, or
&quot;namespace::*&quot; will match all keys in a given namespace.

## Examples of file attribute matcher strings and results

- `&quot;*&quot;`: matches all attributes.
- `&quot;standard::is-hidden&quot;`: matches only the key is-hidden in the
standard namespace.
- `&quot;standard::type,unix::*&quot;`: matches the type key in the standard
namespace and all keys in the unix namespace.

<function name="g_file_copy">
<description>
Copies the file @source to the location specified by @destination.
Can not handle recursive copies of directories.

If the flag %G_FILE_COPY_OVERWRITE is specified an already
existing @destination file is overwritten.

If the flag %G_FILE_COPY_NOFOLLOW_SYMLINKS is specified then symlinks
will be copied as symlinks, otherwise the target of the
@source symlink will be copied.

If the flag %G_FILE_COPY_ALL_METADATA is specified then all the metadata
that is possible to copy is copied, not just the default subset (which,
for instance, does not include the owner, see #GFileInfo).

If @cancellable is not %NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error %G_IO_ERROR_CANCELLED will be returned.

If @progress_callback is not %NULL, then the operation can be monitored
by setting this to a #GFileProgressCallback function.
@progress_callback_data will be passed to this function. It is guaranteed
that this callback will be called after all data has been transferred with
the total number of bytes copied during the operation.

If the @source file does not exist, then the %G_IO_ERROR_NOT_FOUND error
is returned, independent on the status of the @destination.

If %G_FILE_COPY_OVERWRITE is not specified and the target exists, then
the error %G_IO_ERROR_EXISTS is returned.

If trying to overwrite a file over a directory, the %G_IO_ERROR_IS_DIRECTORY
error is returned. If trying to overwrite a directory with a directory the
%G_IO_ERROR_WOULD_MERGE error is returned.

If the source is a directory and the target does not exist, or
%G_FILE_COPY_OVERWRITE is specified and the target is a file, then the
%G_IO_ERROR_WOULD_RECURSE error is returned.

If you are interested in copying the #GFile object itself (not the on-disk
file), see g_file_dup().

Creates a new file and returns an output stream for writing to it.

By default files created are generally readable by everyone,

If a file or directory with this name already exists the
%G_IO_ERROR_EXISTS error will be returned. Some file systems don't
allow all file names, and may return an %G_IO_ERROR_INVALID_FILENAME
error, and if the name is to long %G_IO_ERROR_FILENAME_TOO_LONG will
be returned. Other errors are possible too, and depend on what kind
of filesystem the file is on.

Gets the requested information about the files in a directory.
The result is a #GFileEnumerator object that will give out

The @attributes value is a string that specifies the file
attributes that should be gathered. It is not an error if
it's not possible to read a particular requested attribute
from a file - it just won't be set. @attributes should
be a comma-separated list of attributes or attribute wildcards.
The wildcard &quot;*&quot; means all attributes, and a wildcard like
&quot;standard::*&quot; means all attributes in the standard namespace.
An example attribute query be &quot;standard::*,owner::user&quot;.
The standard attributes are available as defines, like
%G_FILE_ATTRIBUTE_STANDARD_NAME. %G_FILE_ATTRIBUTE_STANDARD_NAME should
always be specified if you plan to call g_file_enumerator_get_child() or
g_file_enumerator_iterate() on the returned enumerator.

If @cancellable is not %NULL, then the operation can be cancelled

<function name="g_file_enumerator_iterate">
<description>
This is a version of g_file_enumerator_next_file() that's easier to
use correctly from C programs.  With g_file_enumerator_next_file(),
the gboolean return value signifies &quot;end of iteration or error&quot;, which
requires allocation of a temporary #GError.

In contrast, with this function, a %FALSE return from
g_file_enumerator_iterate() *always* means
&quot;error&quot;.  End of iteration is signaled by @out_info or @out_child being %NULL.

Another crucial difference is that the references for @out_info and
@out_child are owned by @direnum (they are cached as hidden
properties).  You must not unref them in your own code.  This makes
memory management significantly easier for C code in combination
with loops.

Finally, this function optionally allows retrieving a #GFile as
well.

You must specify at least one of @out_info or @out_child.

The code pattern for correctly using g_file_enumerator_iterate() from C
is:

|[
direnum = g_file_enumerate_children (file, ...);
while (TRUE)
{
GFileInfo *info;
if (!g_file_enumerator_iterate (direnum, &amp;info, NULL, cancellable, error))
goto out;
if (!info)
break;
... do stuff with &quot;info&quot;; do not unref it! ...

g_object_unref (direnum); // Note: frees the last @info

See the documentation of #GFileEnumerator for information about the
order of returned files.

On error, returns %NULL and sets @error to the error. If the
enumerator is at the end, %NULL will be returned and @error will
be unset.

<function name="g_file_enumerator_next_files_async">
<description>
Request information for a number of files from the enumerator asynchronously.
When all i/o for the operation is finished the @callback will be called with
the requested information. 

See the documentation of #GFileEnumerator for information about the
order of returned files.

The callback can be called with less than @num_files files in case of error
or at the end of the enumerator. In case of a partial error the callback will
be called with any succeeding items and no error, and on the next request the
error will be reported. If a request is cancelled the callback will be called
with %G_IO_ERROR_CANCELLED.

During an async request no other sync and async calls are allowed, and will
result in %G_IO_ERROR_PENDING errors. 

Any outstanding i/o request with higher priority (lower numerical value) will
be executed before an outstanding request with lower priority. Default
priority is %G_PRIORITY_DEFAULT.

Gets the base name (the last component of the path) for a given #GFile.

If called for the top level of a system (such as the filesystem root
or a uri like sftp://host/) it will return a single directory separator
(and on Windows, possibly a drive letter).

The base name is a byte string (not UTF-8). It has no defined encoding
or rules other than it may not contain zero bytes.  If you want to use
filenames in a user interface you should use the display name that you
can get by requesting the %G_FILE_ATTRIBUTE_STANDARD_DISPLAY_NAME
attribute with g_file_query_info().

<function name="g_file_get_parse_name">
<description>
Gets the parse name of the @file.
A parse name is a UTF-8 string that describes the
file such that one can get the #GFile back using
g_file_parse_name().

This is generally used to show the #GFile as a nice
full-pathname kind of string in a user interface,
like in a location entry.

For local files with names that can safely be converted
to UTF-8 the pathname is used, otherwise the IRI is used
(a form of URI that allows UTF-8 characters unescaped).

This call does no blocking I/O.

Common schemes include &quot;file&quot;, &quot;http&quot;, &quot;ftp&quot;, etc.

The scheme can be different from the one used to construct the #GFile,
in that it might be replaced with one that is logically equivalent to the #GFile.

<description>
Checks whether @file has the prefix specified by @prefix.

In other words, if the names of initial elements of @file's
pathname match @prefix. Only full pathname elements are matched,
so a path like /foo is not considered a prefix of /foobar, only
of /foo/bar.

A #GFile is not a prefix of itself. If you want to check for
equality, use g_file_equal().

This call does no I/O, as it works purely on names. As such it can
sometimes return %FALSE even if @file is inside a @prefix (from a
filesystem point of view), because the prefix of @file is an alias
of @prefix.

Queries a file io stream for the given @attributes.
This function blocks while querying the stream. For the asynchronous

While the stream is blocked, the stream will set the pending flag
internally, and any other operations on the stream will fail with
%G_IO_ERROR_PENDING.

Can fail if the stream was already closed (with @error being set to
%G_IO_ERROR_CLOSED), the stream has pending operations (with @error being
set to %G_IO_ERROR_PENDING), or if querying info is not supported for
the stream's interface (with @error being set to %G_IO_ERROR_NOT_SUPPORTED). I
all cases of failure, %NULL will be returned.

If @cancellable is not %NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation

Checks to see if a file is native to the platform.

A native file is one expressed in the platform-native filename format,

as it might be on a locally mounted remote filesystem.

On some systems non-native files may be available using the native
filesystem via a userspace filesystem (FUSE), in these cases this call
will return %FALSE, but g_file_get_path() will still return a native path.

It does not make sense for @flags to contain
%G_FILE_MONITOR_WATCH_HARD_LINKS, since hard links can not be made to
directories.  It is not possible to monitor all the files in a
directory for changes made via hard links; if you want to do this then
you must register individual watches with g_file_monitor().

filename (ie, a hard link). Without this flag, you can only rely on
changes made through the filename contained in @file to be

<function name="g_file_move">
<description>
Tries to move the file or directory @source to the location specified
by @destination. If native move operations are supported then this is
used, otherwise a copy + delete fallback is used. The native
implementation may support moving directories (for instance on moves
inside the same filesystem), but the fallback code does not.

If the flag %G_FILE_COPY_OVERWRITE is specified an already
existing @destination file is overwritten.

If @cancellable is not %NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error %G_IO_ERROR_CANCELLED will be returned.

If @progress_callback is not %NULL, then the operation can be monitored
by setting this to a #GFileProgressCallback function.
@progress_callback_data will be passed to this function. It is
guaranteed that this callback will be called after all data has been
transferred with the total number of bytes copied during the operation.

If the @source file does not exist, then the %G_IO_ERROR_NOT_FOUND
error is returned, independent on the status of the @destination.

If %G_FILE_COPY_OVERWRITE is not specified and the target exists,
then the error %G_IO_ERROR_EXISTS is returned.

If trying to overwrite a file over a directory, the %G_IO_ERROR_IS_DIRECTORY
error is returned. If trying to overwrite a directory with a directory the
%G_IO_ERROR_WOULD_MERGE error is returned.

If the source is a directory and the target does not exist, or
%G_FILE_COPY_OVERWRITE is specified and the target is a file, then
the %G_IO_ERROR_WOULD_RECURSE error may be returned (if the native
move operation isn't available).

This function blocks while querying the stream. For the asynchronous 
version of this function, see g_file_output_stream_query_info_async(). 
While the stream is blocked, the stream will set the pending flag 
internally, and any other operations on the stream will fail with 
%G_IO_ERROR_PENDING.

Can fail if the stream was already closed (with @error being set to 
%G_IO_ERROR_CLOSED), the stream has pending operations (with @error being
set to %G_IO_ERROR_PENDING), or if querying info is not supported for 
the stream's interface (with @error being set to %G_IO_ERROR_NOT_SUPPORTED). In
all cases of failure, %NULL will be returned.

If @cancellable is not %NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error %G_IO_ERROR_CANCELLED will be set, and %NULL will 
be returned.

<function name="g_file_query_exists">
<description>
Utility function to check if a particular file exists. This is
implemented using g_file_query_info() and as such does blocking I/O.

Note that in many cases it is [racy to first check for file existence](https://en.wikipedia.org/wiki/Time_of_check_to_time_of_use)
and then execute something based on the outcome of that, because the
file might have been created or removed in between the operations. The
general approach to handling that is to not check, but just do the
operation and handle the errors as they come.

As an example of race-free checking, take the case of reading a file,
and if it doesn't exist, creating it. There are two racy versions: read
it, and on error create it; and: check if it exists, if not create it.
These can both result in two processes creating the file (with perhaps
a partially written file as the result). The correct approach is to
always try to create the file with g_file_create() which will either
atomically create the file or fail with a %G_IO_ERROR_EXISTS error.

However, in many cases an existence check is useful in a user interface,
for instance to make a menu item sensitive/insensitive, so that you don't
have to fool users that something is possible and then just show an error
dialog. If you do this, you should make sure to also handle the errors
that can happen due to races when you execute the operation.

<function name="g_file_query_filesystem_info">
<description>
Similar to g_file_query_info(), but obtains information
about the filesystem the @file is on, rather than the file itself.
For instance the amount of space available and the type of
the filesystem.

The @attributes value is a string that specifies the attributes
that should be gathered. It is not an error if it's not possible
to read a particular requested attribute from a file - it just
won't be set. @attributes should be a comma-separated list of
attributes or attribute wildcards. The wildcard &quot;*&quot; means all
attributes, and a wildcard like &quot;filesystem::*&quot; means all attributes
in the filesystem namespace. The standard namespace for filesystem
attributes is &quot;filesystem&quot;. Common attributes of interest are
%G_FILE_ATTRIBUTE_FILESYSTEM_SIZE (the total size of the filesystem
in bytes), %G_FILE_ATTRIBUTE_FILESYSTEM_FREE (number of bytes available),
and %G_FILE_ATTRIBUTE_FILESYSTEM_TYPE (type of the filesystem).

If @cancellable is not %NULL, then the operation can be cancelled
by triggering the cancellable object from another thread. If the
operation was cancelled, the error %G_IO_ERROR_CANCELLED will be
returned.

If the file does not exist, the %G_IO_ERROR_NOT_FOUND error will
be returned. Other errors are possible too, and depend on what
kind of filesystem the file is on.

Gets the requested information about specified @file.
The result is a #GFileInfo object that contains key-value

The @attributes value is a string that specifies the file
attributes that should be gathered. It is not an error if
it's not possible to read a particular requested attribute

If @cancellable is not %NULL, then the operation can be cancelled
by triggering the cancellable object from another thread. If the
operation was cancelled, the error %G_IO_ERROR_CANCELLED will be

For symlinks, normally the information about the target of the
symlink is returned, rather than information about the symlink
itself. However if you pass %G_FILE_QUERY_INFO_NOFOLLOW_SYMLINKS
in @flags the information about the symlink itself will be returned.
Also, for symlinks that point to non-existing files the information
about the symlink itself will be returned.

If the file does not exist, the %G_IO_ERROR_NOT_FOUND error will be
returned. Other errors are possible too, and depend on what kind of
filesystem the file is on.

<function name="g_file_replace">
<description>
Returns an output stream for overwriting the file, possibly
creating a backup copy of the file first. If the file doesn't exist,
it will be created.

This will try to replace the file in the safest way possible so
that any errors during the writing will not affect an already
existing copy of the file. For instance, for local files it
may write to a temporary file and then atomically rename over
the destination when the stream is closed.

By default files created are generally readable by everyone,
but if you pass %G_FILE_CREATE_PRIVATE in @flags the file
will be made readable only to the current user, to the level that
is supported on the target filesystem.

If @cancellable is not %NULL, then the operation can be cancelled
by triggering the cancellable object from another thread. If the
operation was cancelled, the error %G_IO_ERROR_CANCELLED will be
returned.

If you pass in a non-%NULL @etag value and @file already exists, then
this value is compared to the current entity tag of the file, and if
they differ an %G_IO_ERROR_WRONG_ETAG error is returned. This
generally means that the file has been changed since you last read
it. You can get the new etag from g_file_output_stream_get_etag()
after you've finished writing and closed the #GFileOutputStream. When
you load a new file you can use g_file_input_stream_query_info() to
get the etag of the file.

If @make_backup is %TRUE, this function will attempt to make a
backup of the current file before overwriting it. If this fails
a %G_IO_ERROR_CANT_CREATE_BACKUP error will be returned. If you
want to replace anyway, try again with @make_backup set to %FALSE.

If the file is a directory the %G_IO_ERROR_IS_DIRECTORY error will
be returned, and if the file is some other form of non-regular file
then a %G_IO_ERROR_NOT_REGULAR_FILE error will be returned. Some
file systems don't allow all file names, and may return an
%G_IO_ERROR_INVALID_FILENAME error, and if the name is to long
%G_IO_ERROR_FILENAME_TOO_LONG will be returned. Other errors are
possible too, and depend on what kind of filesystem the file is on.

<function name="g_file_replace_contents">
<description>
Replaces the contents of @file with @contents of @length bytes.

If @etag is specified (not %NULL), any existing file must have that etag,
or the error %G_IO_ERROR_WRONG_ETAG will be returned.

If @make_backup is %TRUE, this function will attempt to make a backup
of @file. Internally, it uses g_file_replace(), so will try to replace the
file contents in the safest way possible. For example, atomic renames are
used when replacing local files’ contents.

If @cancellable is not %NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error %G_IO_ERROR_CANCELLED will be returned.

The returned @new_etag can be used to verify that the file hasn't
changed the next time it is saved over.

<description>
Starts an asynchronous replacement of @file with the given
@contents of @length bytes. @etag will replace the document's
current entity tag.

When this operation has completed, @callback will be called with
@user_user data, and the operation can be finalized with
g_file_replace_contents_finish().

triggering the cancellable object from another thread. If the operation
was cancelled, the error %G_IO_ERROR_CANCELLED will be returned.

If @make_backup is %TRUE, this function will attempt to
make a backup of @file.

Note that no copy of @contents will be made, so it must stay valid
until @callback is called. See g_file_replace_contents_bytes_async()

content without waiting for the callback.

When this operation has completed, @callback will be called with
@user_user data, and the operation can be finalized with
g_file_replace_contents_finish().

For details about the behaviour, see g_file_replace() which does the
same thing but returns an output stream only.

Note that in many non-local file cases read and write streams are not
supported, so make sure you really need to do read and write streaming,
rather than just opening for reading or writing.

<function name="g_file_start_mountable">
<description>
Starts a file of type %G_FILE_TYPE_MOUNTABLE.
Using @start_operation, you can request callbacks when, for instance,
passwords are needed during authentication.

If @cancellable is not %NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error %G_IO_ERROR_CANCELLED will be returned.

When the operation is finished, @callback will be called.
You can then call g_file_mount_mountable_finish() to get
the result of the operation.

The encoding of the returned string is proprietary to #GIcon except
in the following two cases

- If @icon is a #GFileIcon, the returned string is a native path
(such as `/path/to/my icon.png`) without escaping
if the #GFile for @icon is a native file.  If the file is not
native, the returned string is the result of g_file_get_uri()
(such as `sftp://path/to/my%20icon.png`).

- If @icon is a #GThemedIcon with exactly one name and no fallbacks,
the encoding is simply the name (such as `network-server`).

<function name="g_initable_init">
<description>
Initializes the object implementing the interface.

This method is intended for language bindings. If writing in C,
g_initable_new() should typically be used instead.

The object must be initialized before any real use after initial
construction, either with this function or g_async_initable_init_async().

Implementations may also support cancellation. If @cancellable is not %NULL,
then initialization can be cancelled by triggering the cancellable object
from another thread. If the operation was cancelled, the error
%G_IO_ERROR_CANCELLED will be returned. If @cancellable is not %NULL and
the object doesn't support cancellable initialization the error
%G_IO_ERROR_NOT_SUPPORTED will be returned.

If the object is not initialized, or initialization returns with an
error, then all operations on the object except g_object_ref() and
g_object_unref() are considered to be invalid, and have undefined
behaviour. See the [introduction][ginitable] for more details.

Callers should not assume that a class which implements #GInitable can be
initialized multiple times, unless the class explicitly documents itself as
supporting this. Generally, a class’ implementation of init() can assume
(and assert) that it will only be called once. Previously, this documentation
recommended all #GInitable implementations should be idempotent; that
recommendation was relaxed in GLib 2.54.

If a class explicitly supports being initialized multiple times, it is
recommended that the method is idempotent: multiple calls with the same
arguments should return the same results. Only the first call initializes
the object; further calls return the result of the first call.

One reason why a class might need to support idempotent initialization is if
it is designed to be used via the singleton pattern, with a
#GObjectClass.constructor that sometimes returns an existing instance.
In this pattern, a caller would expect to be able to call g_initable_init()
on the result of g_object_new(), regardless of whether it is in fact a new
instance.

<function name="g_input_stream_close">
<description>
Closes the stream, releasing resources related to it.

Once the stream is closed, all other operations will return %G_IO_ERROR_CLOSED.
Closing a stream multiple times will not return an error.

Streams will be automatically closed when the last reference
is dropped, but you might want to call this function to make sure 
resources are released as early as possible.

Some streams might keep the backing store of the stream (e.g. a file descriptor)
open after the stream is closed. See the documentation for the individual
stream for details.

On failure the first error that happened will be reported, but the close
operation will finish as much as possible. A stream that failed to
close will still return %G_IO_ERROR_CLOSED for all operations. Still, it
is important to check and report the error to the user.

If @cancellable is not %NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error %G_IO_ERROR_CANCELLED will be returned.
Cancelling a close will still leave the stream closed, but some streams
can use a faster close that doesn't block to e.g. check errors.

<description>
Tries to read @count bytes from the stream into the buffer starting at
@buffer. Will block during this read.

If count is zero returns zero and does nothing. A value of @count
larger than %G_MAXSSIZE will cause a %G_IO_ERROR_INVALID_ARGUMENT error.

On success, the number of bytes read into the buffer is returned.
It is not an error if this is not the same as the requested size, as it
can happen e.g. near the end of a file. Zero is returned on end of file
(or if @count is zero),  but never otherwise.

The returned @buffer is not a nul-terminated string, it can contain nul bytes
at any position, and this function doesn't nul-terminate the @buffer.

If @cancellable is not %NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error %G_IO_ERROR_CANCELLED will be returned. If an
operation was partially finished when the operation was cancelled the
partial result will be returned, without an error.

On error -1 is returned and @error is set accordingly.

On a successful read of @count bytes, or if we reached the end of the
stream,  %TRUE is returned, and @bytes_read is set to the number of bytes
read into @buffer.

If there is an error during the operation %FALSE is returned and @error

As a special exception to the normal conventions for functions that

@bytes_read will be set to the number of bytes that were successfully
read before the error was encountered.  This functionality is only

value of @count larger than %G_MAXSSIZE will cause a
%G_IO_ERROR_INVALID_ARGUMENT error.

On success, a new #GBytes is returned. It is not an error if the
size of this object is not the same as the requested size, as it
can happen e.g. near the end of a file. A zero-length #GBytes is
returned on end of file (or if @count is zero), but never
otherwise.

If @cancellable is not %NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error %G_IO_ERROR_CANCELLED will be returned. If an
operation was partially finished when the operation was cancelled the
partial result will be returned, without an error.

On error %NULL is returned and @error is set accordingly.

Request an asynchronous read of @count bytes from the stream into a

During an async request no other sync and async calls are allowed

Any outstanding I/O request with higher priority (lower numerical

everything after the first dot removed, and with `-` replaced with `_`

Optional API for GIO modules to implement.

Should return a list of all the extension points that may be

This method will not be called in normal use, however it may be
called when probing existing modules and recording which extension
points that this model is used for. This means we won't have to
load and initialize this module unless its needed.

If this function is not implemented by the module the module will
always be loaded, initialized and then unloaded on application
startup so that it can register its extension points during init.

Note that a module need not actually implement all the extension
points that g_io_module_query() returns, since the exact list of
extension may depend on runtime issues. However all extension
points actually implemented must be returned by g_io_module_query()
(if defined).

When installing a module that implements g_io_module_query() you must
run gio-querymodules in order to build the cache files required for
lazy loading.

Since 2.56, this function should be named `g_io_&lt;modulename&gt;_query`, where
`modulename` is the plugin’s filename with the `lib` or `libgio` prefix and
everything after the first dot removed, and with `-` replaced with `_`

<function name="g_io_stream_close">
<description>
Closes the stream, releasing resources related to it. This will also
close the individual input and output streams, if they are not already
closed.

Once the stream is closed, all other operations will return
%G_IO_ERROR_CLOSED. Closing a stream multiple times will not
return an error.

Closing a stream will automatically flush any outstanding buffers
in the stream.

Streams will be automatically closed when the last reference
is dropped, but you might want to call this function to make sure
resources are released as early as possible.

Some streams might keep the backing store of the stream (e.g. a file
descriptor) open after the stream is closed. See the documentation for
the individual stream for details.

On failure the first error that happened will be reported, but the
close operation will finish as much as possible. A stream that failed
to close will still return %G_IO_ERROR_CLOSED for all operations.
Still, it is important to check and report the error to the user,
otherwise there might be a loss of data as all data might not be written.

If @cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error %G_IO_ERROR_CANCELLED will be returned.
Cancelling a close will still leave the stream closed, but some streams
can use a faster close that doesn't block to e.g. check errors.

The default implementation of this method just calls close on the
individual input/output streams.

<function name="g_keyfile_settings_backend_new">
<description>
Creates a keyfile-backed #GSettingsBackend.

The filename of the keyfile to use is given by @filename.

All settings read to or written from the backend must fall under the
path given in @root_path (which must start and end with a slash and
not contain two consecutive slashes).  @root_path may be &quot;/&quot;.

If @root_group is non-%NULL then it specifies the name of the keyfile
group used for keys that are written directly below @root_path.  For
example, if @root_path is &quot;/apps/example/&quot; and @root_group is
&quot;toplevel&quot;, then settings the key &quot;/apps/example/enabled&quot; to a value
of %TRUE will cause the following to appear in the keyfile:

|[
[toplevel]
enabled=true
]|

If @root_group is %NULL then it is not permitted to store keys
directly below the @root_path.

For keys not stored directly below @root_path (ie: in a sub-path),
the name of the subpath (with the final slash stripped) is used as
the name of the keyfile group.  To continue the example, if
&quot;/apps/example/profiles/default/font-size&quot; were set to
12 then the following would appear in the keyfile:

|[
[profiles/default]
font-size=12
]|

The backend will refuse writes (and return writability as being
%FALSE) for keys outside of @root_path and, in the event that
@root_group is %NULL, also for keys directly under @root_path.
Writes will also be refused if the backend detects that it has the
inability to rewrite the keyfile (ie: the containing directory is not
writable).

There is no checking done for your key namespace clashing with the
syntax of the key file format.  For example, if you have '[' or ']'
characters in your path names or '=' in your key names you may be in
trouble.

The backend reads default values from a keyfile called `defaults` in
the directory specified by the #GKeyfileSettingsBackend:defaults-dir property,
and a list of locked keys from a text file with the name `locks` in
the same location.

<function name="g_list_model_items_changed">
<description>
Emits the #GListModel::items-changed signal on @list.

This function should only be called by classes implementing
#GListModel. It has to be called after the internal representation
of @list has been updated, because handlers connected to this signal
might query the new state of the list.

Implementations must only make changes to the model (as visible to
its consumer) in places that will not cause problems for that
consumer.  For models that are driven directly by a write API (such
as #GListStore), changes can be reported in response to uses of that
API.  For models that represent remote data, changes should only be
made from a fresh mainloop dispatch.  It is particularly not
permitted to make changes in response to a call to the #GListModel
consumer API.

Stated another way: in general, it is assumed that code making a
series of accesses to the model via the API, without returning to the
mainloop, and without calling other code, will continue to view the
same contents of the model.

Gets the size of the currently allocated data area (available from

You probably don't want to use this function on resizable streams.
See g_memory_output_stream_get_data_size() instead.  For resizable
streams the size returned by this function is an implementation
detail and may be change at any time in response to operations on the
stream.

If the stream is fixed-sized (ie: no realloc was passed to
g_memory_output_stream_new()) then this is the maximum size of the
stream and further writes will return %G_IO_ERROR_NO_SPACE.

<function name="g_memory_output_stream_new">
<description>
Creates a new #GMemoryOutputStream.

In most cases this is not the function you want.  See
g_memory_output_stream_new_resizable() instead.

If @data is non-%NULL, the stream will use that for its internal storage.

If @realloc_fn is non-%NULL, it will be used for resizing the internal
storage when necessary and the stream will be considered resizable.
In that case, the stream will start out being (conceptually) empty.
@size is used only as a hint for how big @data is.  Specifically,
seeking to the end of a newly-created stream will seek to zero, not
@size.  Seeking past the end of the stream and then writing will
introduce a zero-filled gap.

If @realloc_fn is %NULL then the stream is fixed-sized.  Seeking to
the end will seek to @size exactly.  Writing past the end will give
an 'out of space' error.  Attempting to seek past the end will fail.
Unlike the resizable case, seeking to an offset within the stream and
writing will preserve the bytes passed in as @data before that point
and will return them as part of g_memory_output_stream_steal_data().
If you intend to seek you should probably therefore ensure that @data
is properly initialised.

It is probably only meaningful to provide @data and @size in the case
that you want a fixed-sized stream.  Put another way: if @realloc_fn
is non-%NULL then it makes most sense to give @data as %NULL and
@size as 0 (allowing #GMemoryOutputStream to do the initial
allocation for itself).

Inserts @item into @menu.

The &quot;insertion&quot; is actually done by copying all of the attribute and
link values of @item and using them to form a new item within @menu.
As such, @item itself is not really inserted, but rather, a menu item
that is exactly the same as the one presently described by @item.

This means that @item is essentially useless after the insertion
occurs.  Any changes you make to it are ignored unless it is inserted
again (at which point its updated values will be copied).

You should probably just free @item once you're done.

There are many convenience functions to take care of common cases.

<function name="g_menu_item_new_section">
<description>
Creates a new #GMenuItem representing a section.

This is a convenience API around g_menu_item_new() and
g_menu_item_set_section().

The effect of having one menu appear as a section of another is
exactly as it sounds: the items from @section become a direct part of
the menu that @menu_item is added to.

Visual separation is typically displayed between two non-empty
sections.  If @label is non-%NULL then it will be encorporated into
this visual indication.  This allows for labeled subsections of a
menu.

As a simple example, consider a typical &quot;Edit&quot; menu from a simple
program.  It probably contains an &quot;Undo&quot; and &quot;Redo&quot; item, followed by
a separator, followed by &quot;Cut&quot;, &quot;Copy&quot; and &quot;Paste&quot;.

This would be accomplished by creating three #GMenu instances.  The
first would be populated with the &quot;Undo&quot; and &quot;Redo&quot; items, and the
second with the &quot;Cut&quot;, &quot;Copy&quot; and &quot;Paste&quot; items.  The first and
second menus would then be added as submenus of the third.  In XML
format, this would look something like the following:
|[
&lt;menu id='edit-menu'&gt;
&lt;section&gt;
&lt;item label='Undo'/&gt;
&lt;item label='Redo'/&gt;
&lt;/section&gt;
&lt;section&gt;
&lt;item label='Cut'/&gt;
&lt;item label='Copy'/&gt;
&lt;item label='Paste'/&gt;
&lt;/section&gt;
&lt;/menu&gt;
]|

The following example is exactly equivalent.  It is more illustrative
of the exact relationship between the menus and items (keeping in
mind that the 'link' element defines a new menu that is linked to the
containing one).  The style of the second example is more verbose and
difficult to read (and therefore not recommended except for the
purpose of understanding what is really going on).
|[
&lt;menu id='edit-menu'&gt;
&lt;item&gt;
&lt;link name='section'&gt;
&lt;item label='Undo'/&gt;
&lt;item label='Redo'/&gt;

the named action with the &quot;target&quot; attribute given as the parameter
to the action invocation.  If the &quot;target&quot; attribute is not set then
the action is invoked with no parameter.

If the action has no state then the menu item is usually drawn as a
plain menu item (ie: with no additional decoration).

If the action has a boolean state then the menu item is usually drawn
as a toggle menu item (ie: with a checkmark or equivalent
indication).  The item should be marked as 'toggled' or 'checked'
when the boolean state is %TRUE.

If the action has a string state then the menu item is usually drawn
as a radio menu item (ie: with a radio bullet or equivalent
indication).  The item should be marked as 'selected' when the string
state is equal to the value of the @target property.

See g_menu_item_set_action_and_target() or
g_menu_item_set_detailed_action() for two equivalent calls that are
probably more convenient for most uses.

<function name="g_menu_item_set_attribute">
<description>
Sets or unsets an attribute on @menu_item.

The attribute to set or unset is specified by @attribute. This
can be one of the standard attribute names %G_MENU_ATTRIBUTE_LABEL,
%G_MENU_ATTRIBUTE_ACTION, %G_MENU_ATTRIBUTE_TARGET, or a custom
attribute name.
Attribute names are restricted to lowercase characters, numbers
and '-'. Furthermore, the names must begin with a lowercase character,
must not end with a '-', and must not contain consecutive dashes.

If @format_string is non-%NULL then the proper position parameters
are collected to create a #GVariant instance to use as the attribute
value.  If it is %NULL then the positional parameterrs are ignored
and the named attribute is unset.

See also g_menu_item_set_attribute_value() for an equivalent call
that directly accepts a #GVariant.

Requests emission of the #GMenuModel::items-changed signal on @model.

This function should never be called except by #GMenuModel

The implementation should update its internal representation of the
menu before emitting the signal.  The implementation should further
expect to receive queries about the new state of the menu (and
particularly added menu items) while signal handlers are running.

The implementation must dispatch this call directly from a mainloop
entry and not in response to calls -- particularly those from the
#GMenuModel API.  Said another way: the menu must not change while
user code is running without returning to the mainloop.

<function name="g_mount_is_shadowed">
<description>
Determines if @mount is shadowed. Applications or libraries should
avoid displaying @mount in the user interface if it is shadowed.

A mount is said to be shadowed if there exists one or more user
visible objects (currently #GMount objects) with a root that is
inside the root of @mount.

One application of shadow mounts is when exposing a single file
system that is used to address several logical volumes. In this
situation, a #GVolumeMonitor implementation would create two
#GVolume objects (for example, one for the camera functionality of
the device and one for a SD card reader on the device) with
activation URIs `gphoto2://[usb:001,002]/store1/`
and `gphoto2://[usb:001,002]/store2/`. When the
underlying mount (with root
`gphoto2://[usb:001,002]/`) is mounted, said
#GVolumeMonitor implementation would create two #GMount objects
(each with their root matching the corresponding volume activation
root) that would shadow the original mount.

The proxy monitor in GVfs 2.26 and later, automatically creates and
manage shadow mounts (and shadows the underlying mount) if the
activation root on a #GVolume is set.

(The port component of @host_and_port can also be specified as a
service name rather than as a numeric port, but this functionality
is deprecated, because it depends on the contents of /etc/services,
which is generally quite sparse on platforms other than Linux.)

Attempts to determine whether or not the host pointed to by

This may return %TRUE even when #GNetworkMonitor:network-available
is %FALSE, if, for example, @monitor can determine that
@connectable refers to a host on a local network.

If @monitor believes that an attempt to connect to @connectable
will succeed, it will return %TRUE. Otherwise, it will return
%FALSE and set @error to an appropriate error (such as
%G_IO_ERROR_HOST_UNREACHABLE).

Note that although this does not attempt to connect to
@connectable, it may still block for a brief period of time (eg,
trying to do multicast DNS on the local network), so if you do not
want to block, you should use g_network_monitor_can_reach_async().

<function name="g_output_stream_close">
<description>
Closes the stream, releasing resources related to it.

Once the stream is closed, all other operations will return %G_IO_ERROR_CLOSED.
Closing a stream multiple times will not return an error.

Closing a stream will automatically flush any outstanding buffers in the
stream.

Streams will be automatically closed when the last reference
is dropped, but you might want to call this function to make sure 
resources are released as early as possible.

Some streams might keep the backing store of the stream (e.g. a file descriptor)
open after the stream is closed. See the documentation for the individual
stream for details.

On failure the first error that happened will be reported, but the close
operation will finish as much as possible. A stream that failed to
close will still return %G_IO_ERROR_CLOSED for all operations. Still, it
is important to check and report the error to the user, otherwise
there might be a loss of data as all data might not be written.

If @cancellable is not %NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error %G_IO_ERROR_CANCELLED will be returned.
Cancelling a close will still leave the stream closed, but there some streams
can use a faster close that doesn't block to e.g. check errors. On
cancellation (as with any error) there is no guarantee that all written
data will reach the target.

Tries to write @count bytes from @buffer into the stream. Will block

If count is 0, returns 0 and does nothing. A value of @count
larger than %G_MAXSSIZE will cause a %G_IO_ERROR_INVALID_ARGUMENT error.

On success, the number of bytes written to the stream is returned.
It is not an error if this is not the same as the requested size, as it
can happen e.g. on a partial I/O error, or if there is not enough

is written or an error occurs; 0 is never returned (unless
@count is 0).

If @cancellable is not %NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error %G_IO_ERROR_CANCELLED will be returned. If an
operation was partially finished when the operation was cancelled the
partial result will be returned, without an error.

On error -1 is returned and @error is set accordingly.

<description>
Request an asynchronous write of @count bytes from @buffer into

You can then call g_output_stream_write_finish() to get the result of the 
operation.

During an async request no other sync and async calls are allowed, 
and will result in %G_IO_ERROR_PENDING errors. 

A value of @count larger than %G_MAXSSIZE will cause a 
%G_IO_ERROR_INVALID_ARGUMENT error.

On success, the number of bytes written will be passed to the
@callback. It is not an error if this is not the same as the 
requested size, as it can happen e.g. on a partial I/O error, 
but generally we try to write as many bytes as requested. 

You are guaranteed that this method will never fail with
%G_IO_ERROR_WOULD_BLOCK - if @stream can't accept more data, the
method will just wait until this changes.

Any outstanding I/O request with higher priority (lower numerical 
value) will be executed before an outstanding request with lower 
priority. Default priority is %G_PRIORITY_DEFAULT.

The asynchronous methods have a default fallback that uses threads
to implement asynchronicity, so they are optional for inheriting 
classes. However, if you override one you must override all.

For the synchronous, blocking version of this function, see 
g_output_stream_write().

Note that no copy of @buffer will be made, so it must stay valid
until @callback is called. See g_output_stream_write_bytes_async()
for a #GBytes version that will automatically hold a reference to
the contents (without copying) for the duration of the call.

and will result in %G_IO_ERROR_PENDING errors.

On success, the number of bytes written will be passed to the
@callback. It is not an error if this is not the same as the
requested size, as it can happen e.g. on a partial I/O error,
but generally we try to write as many bytes as requested.

You are guaranteed that this method will never fail with
%G_IO_ERROR_WOULD_BLOCK — if @stream can't accept more data, the
method will just wait until this changes.

Any outstanding I/O request with higher priority (lower numerical
value) will be executed before an outstanding request with lower
priority. Default priority is %G_PRIORITY_DEFAULT.

The asynchronous methods have a default fallback that uses threads
to implement asynchronicity, so they are optional for inheriting
classes. However, if you override one you must override all.

For the synchronous, blocking version of this function, see
g_output_stream_writev().

Note that no copy of @vectors will be made, so it must stay valid
until @callback is called.

`direct://`, where &lt;protocol&gt; could be http, rtsp, socks

If you don't know what network protocol is being used on the
socket, you should use `none` as the URI protocol.
In this case, the resolver might still return a generic proxy type
(such as SOCKS), but would not return protocol-specific proxy types
(such as http).

`direct://` is used when no proxy is needed.
Direct connection should not be attempted unless it is part of the
returned array of proxies.

Synchronously performs a DNS SRV lookup for the given @service and

@domain may be an ASCII-only or UTF-8 hostname. Note also that the
@service and @protocol arguments do not include the leading underscore
that appears in the actual DNS entry.

On success, g_resolver_lookup_service() will return a non-empty #GList of
#GSrvTarget, sorted in order of preference. (That is, you should
attempt to connect to the first target first, then the second if
the first fails, etc.)

If the DNS resolution fails, @error (if non-%NULL) will be set to
a value from #GResolverError and %NULL will be returned.

If @cancellable is non-%NULL, it can be used to cancel the
operation, in which case @error (if non-%NULL) will be set to
%G_IO_ERROR_CANCELLED.

If you are planning to connect to the service, it is usually easier
to create a #GNetworkService and use its #GSocketConnectable
interface.

g_settings_backend_changed().  These two calls can be used
interchangeably if exactly one item has changed (although in that
case g_settings_backend_changed() is definitely preferred).

For efficiency reasons, the implementation should strive for @path to
be as long as possible (ie: the longest common prefix of all of the
keys that were changed) but this is not strictly required.

<function name="g_settings_backend_path_changed">
<description>
Signals that all keys below a given path may have possibly changed.
Backend implementations should call this if an entire path of keys
have possibly changed their values.

@path must be a valid path (ie starting and ending with a slash and
not containing '//').

The meaning of this signal is that any of the key which has a name
starting with @path may have changed.

The same rules for when notifications must occur apply as per
g_settings_backend_changed().  This call might be an appropriate
reasponse to a 'reset' call but implementations are also free to
explicitly list the keys that were affected by that call if they can
easily do so.

For efficiency reasons, the implementation should strive for @path to
be as long as possible (ie: the longest common prefix of all of the
keys that were changed) but this is not strictly required.  As an
example, if this function is called with the path of &quot;/&quot; then every
single key in the application will be notified of a possible change.

<function name="g_settings_bind">
<description>
Create a binding between the @key in the @settings object
and the property @property of @object.

The binding uses the default GIO mapping functions to map
between the settings and property values. These functions
handle booleans, numeric types and string types in a
straightforward way. Use g_settings_bind_with_mapping() if
you need a custom mapping, or map between types that are not
supported by the default mapping functions.

Unless the @flags include %G_SETTINGS_BIND_NO_SENSITIVITY, this
function also establishes a binding between the writability of
@key and the &quot;sensitive&quot; property of @object (if @object has
a boolean property by that name). See g_settings_bind_writable()
for more details about writable bindings.

Note that the lifecycle of the binding is tied to @object,
and that you can have only one binding per object property.
If you bind the same property twice on the same object, the second
binding overrides the first one.

Create a binding between the writability of @key in the

The property must be boolean; &quot;sensitive&quot; or &quot;visible&quot;
properties of widgets are the most likely candidates.

Writable bindings are always uni-directional; changes of the
writability of the setting will be propagated to the object
property, not the other way.

When the @inverted argument is %TRUE, the binding inverts the
value as it passes from the setting to the object, i.e. @property
will be set to %TRUE if the key is not writable.

The value of the key becomes the state of the action and the action
is enabled when the key is writable.  Changing the state of the
action results in the key being written to.  Changes to the value or
writability of the key cause appropriate change notifications to be
emitted for the action.

For boolean-valued keys, action activations take no parameter and
result in the toggling of the value.  For all other types,
activations take the new value for the key (which must have the
correct type).

Comparing the return values of g_settings_get_default_value() and
g_settings_get_value() is not sufficient for determining if a value

<function name="g_settings_get_mapped">
<description>
Gets the value that is stored at @key in @settings, subject to
application-level validation/mapping.

You should use this function when the application needs to perform
some processing on the value of the key (for example, parsing).  The
@mapping function performs that processing.  If the function
indicates that the processing was unsuccessful (due to a parse error,
for example) then the mapping is tried again with another value.

This allows a robust 'fall back to defaults' behaviour to be
implemented somewhat automatically.

The first value that is tried is the user's setting for the key.  If
the mapping function fails to map this value, other values may be
tried in an unspecified order (system or site defaults, translated
schema default values, untranslated schema default values, etc).

If the mapping function fails for all possible values, one additional
attempt is made: the mapping function is called with a %NULL value.
If the mapping function still indicates failure at this point then
the application will be aborted.

The result parameter for the @mapping function is pointed to a
#gpointer which is initially set to %NULL.  The same pointer is given
to each invocation of @mapping.  The final value of that #gpointer is
what is returned by this function.  %NULL is valid; it is returned
just as any other value would be.

It is made available for advanced use-cases (such as plugin systems
that want to provide access to schemas loaded from custom locations,
etc).

At the most basic level, a #GSettings object is a pure composition of
4 things: a #GSettingsSchema, a #GSettingsBackend, a path within that
backend, and a #GMainContext to which signals are dispatched.

This constructor therefore gives you full control over constructing
#GSettings instances.  The first 3 parameters are given directly as
@schema, @backend and @path, and the main context is taken from the
thread-default (as per g_settings_new()).

If @backend is %NULL then the default backend is used.

If @path is %NULL then the path from the schema is used.  It is an
error if @path is %NULL and the schema has no path of its own or if
@path is non-%NULL and not equal to the path that the schema does
have.

Creates a new #GSettings object with the schema specified by

Creating a #GSettings object with a different backend allows accessing
settings from a database other than the usual one. For example, it may make
sense to pass a backend corresponding to the &quot;defaults&quot; settings database on
the system to get a settings object that modifies the system default
settings instead of the settings for this user.

<function name="g_settings_schema_key_get_range">
<description>
Queries the range of a key.

This function will return a #GVariant that fully describes the range
of values that are valid for @key.

The type of #GVariant returned is `(sv)`. The string describes
the type of range restriction in effect. The type and meaning of
the value contained in the variant depends on the string.

If the string is `'type'` then the variant contains an empty array.
The element type of that empty array is the expected type of value
and all values of that type are valid.

If the string is `'enum'` then the variant contains an array
enumerating the possible values. Each item in the array is
a possible valid value and no other values are valid.

If the string is `'flags'` then the variant contains an array. Each
item in the array is a value that may appear zero or one times in an
array to be used as the value for this key. For example, if the
variant contained the array `['x', 'y']` then the valid values for
the key would be `[]`, `['x']`, `['y']`, `['x', 'y']` and
`['y', 'x']`.

Finally, if the string is `'range'` then the variant contains a pair
of like-typed values -- the minimum and maximum permissible values
for this key.

This information should not be used by normal programs.  It is
considered to be a hint for introspection purposes.  Normal programs
should already know what is permitted by their own schema.  The
format may change in any way in the future -- but particularly, new
forms may be added to the possibilities described above.

<description>
Attempts to create a new schema source corresponding to the contents

This function is not required for normal uses of #GSettings but it
may be useful to authors of plugin management systems.

The directory should contain a file called `gschemas.compiled` as
produced by the [glib-compile-schemas][glib-compile-schemas] tool.

If @trusted is %TRUE then `gschemas.compiled` is trusted not to be
corrupted. This assumption has a performance advantage, but can result
in crashes or inconsistent behaviour in the case of a corrupted file.
Generally, you should set @trusted to %TRUE for files installed by the
system and to %FALSE for files in the home directory.

In either case, an empty file or some types of corruption in the file will
result in %G_FILE_ERROR_INVAL being returned.

If @parent is non-%NULL then there are two effects.

First, if g_settings_schema_source_lookup() is called with the
@recursive flag set to %TRUE and the schema can not be found in the
source, the lookup will recurse to the parent.

Second, any references to other schemas specified within this
source (ie: `child` or `extends`) references may be resolved
from the @parent.

For this second reason, except in very unusual situations, the
@parent should probably be given as the default schema source, as
returned by g_settings_schema_source_get_default().

<function name="g_socket_bind">
<description>
When a socket is created it is attached to an address family, but it
doesn't have an address in this family. g_socket_bind() assigns the
address (sometimes called name) of the socket.

It is generally required to bind to a local address before you can
receive connections. (See g_socket_listen() and g_socket_accept() ).
In certain situations, you may also want to bind a socket that will be
used to initiate connections, though this is not normally required.

If @socket is a TCP socket, then @allow_reuse controls the setting
of the `SO_REUSEADDR` socket option; normally it should be %TRUE for
server sockets (sockets that you will eventually call
g_socket_accept() on), and %FALSE for client sockets. (Failing to
set this flag on a server socket may cause g_socket_bind() to return
%G_IO_ERROR_ADDRESS_IN_USE if the server program is stopped and then
immediately restarted.)

If @socket is a UDP socket, then @allow_reuse determines whether or
not other UDP sockets can be bound to the same address at the same
time. In particular, you can have several UDP sockets bound to the
same address, and they will all receive all of the multicast and
broadcast packets sent to that address. (The behavior of unicast
UDP packets to an address with multiple listeners is not defined.)

<description>
Enable proxy protocols to be handled by the application. When the
indicated proxy protocol is returned by the #GProxyResolver,
#GSocketClient will consider this protocol as supported but will
not try to find a #GProxy instance to handle handshaking. The
application must check for this case by calling
g_socket_connection_get_remote_address() on the returned
#GSocketConnection, and seeing if it's a #GProxyAddress of the
appropriate type, to determine whether or not it needs to handle
the proxy handshaking itself.

This should be used for proxy protocols that are dialects of
another protocol such as HTTP proxy. It also allows cohabitation of
proxy protocols that are reused between protocols. A good example
is HTTP. It can be used to proxy HTTP, FTP and Gopher and can also
be use as generic socket proxy through the HTTP CONNECT method.

When the proxy is detected as being an application proxy, TLS handshake
will be skipped. This is required to let the application do the proxy
specific handshake.

<description>
Tries to resolve the @connectable and make a network connection to it.

Upon a successful connection, a new #GSocketConnection is constructed
and returned.  The caller owns this new object and must drop their
reference to it when finished with it.

The type of the #GSocketConnection object returned depends on the type of
the underlying socket that is used. For instance, for a TCP/IP connection
it will be a #GTcpConnection.

The socket created will be the same family as the address that the
@connectable resolves to, unless family is set with g_socket_client_set_family()
or indirectly via g_socket_client_set_local_address(). The socket type
defaults to %G_SOCKET_TYPE_STREAM but can be set with
g_socket_client_set_socket_type().

If a local address is specified with g_socket_client_set_local_address() the
socket will be bound to this address before connecting.

<description>
This is a helper function for g_socket_client_connect().

Attempts to create a TCP connection to the named host.

@host_and_port may be in any of a number of recognized formats; an IPv6
address, an IPv4 address, or a domain name (in which case a DNS
lookup is performed).  Quoting with [] is supported for all address
types.  A port override may be specified in the usual way with a
colon.  Ports may be given as decimal numbers or symbolic names (in
which case an /etc/services lookup is performed).

If no port override is given in @host_and_port then @default_port will be
used as the port number to connect to.

In general, @host_and_port is expected to be provided by the user (allowing
them to give the hostname, and a port override if necessary) and
@default_port is expected to be provided by the application.

In the case that an IP address is given, a single connection
attempt is made.  In the case that a name is given, multiple
connection attempts may be made, in turn and according to the
number of address records in DNS, until a connection succeeds.

Upon a successful connection, a new #GSocketConnection is constructed
and returned.  The caller owns this new object and must drop their
reference to it when finished with it.

In the event of any failure (DNS error, service not found, no hosts
connectable) %NULL is returned and @error (if non-%NULL) is set
accordingly.

This is a helper function for g_socket_client_connect().

Attempts to create a TCP connection with a network URI.

@uri may be any valid URI containing an &quot;authority&quot; (hostname/port)
component. If a port is not specified in the URI, @default_port
will be used. TLS will be negotiated if #GSocketClient:tls is %TRUE.
(#GSocketClient does not know to automatically assume TLS for
certain URI schemes.)

Using this rather than g_socket_client_connect() or
g_socket_client_connect_to_host() allows #GSocketClient to
determine when to use application-specific proxy protocols.

Upon a successful connection, a new #GSocketConnection is constructed
and returned.  The caller owns this new object and must drop their
reference to it when finished with it.

In the event of any failure (DNS error, service not found, no hosts
connectable) %NULL is returned and @error (if non-%NULL) is set
accordingly.

<description>
Sets whether @client creates TLS (aka SSL) connections. If @tls is
%TRUE, @client will wrap its connections in a #GTlsClientConnection
and perform a TLS handshake when connecting.

Note that since #GSocketClient must return a #GSocketConnection,
but #GTlsClientConnection is not a #GSocketConnection, this
actually wraps the resulting #GTlsClientConnection in a
#GTcpWrapperConnection when returning it. You can use
g_tcp_wrapper_connection_get_base_io_stream() on the return value
to extract the #GTlsClientConnection.

If you need to modify the behavior of the TLS handshake (eg, by
setting a client-side certificate to use, or connecting to the
#GTlsConnection::accept-certificate signal), you can connect to
@client's #GSocketClient::event signal and wait for it to be
emitted with %G_SOCKET_CLIENT_TLS_HANDSHAKING, which will give you
a chance to see the #GTlsClientConnection before the handshake
starts.

<function name="g_socket_close">
<description>
Closes the socket, shutting down any active connection.

Closing a socket does not wait for all outstanding I/O operations
to finish, so the caller should not rely on them to be guaranteed
to complete even if the close returns with no error.

Once the socket is closed, all other operations will return
%G_IO_ERROR_CLOSED. Closing a socket multiple times will not
return an error.

Sockets will be automatically closed when the last reference
is dropped, but you might want to call this function to make sure
resources are released as early as possible.

Beware that due to the way that TCP works, it is possible for
recently-sent data to be lost if either you close a socket while the
%G_IO_IN condition is set, or else if the remote connection tries to
send something to you after you close the socket but before it has
finished reading all of the data you sent. There is no easy generic
way to avoid this problem; the easiest fix is to design the network
protocol such that the client will never send data &quot;out of turn&quot;.
Another solution is for the server to half-close the connection by
calling g_socket_shutdown() with only the @shutdown_write flag set,
and then wait for the client to notice this and close its side of the
connection, after which the server can safely call g_socket_close().
(This is what #GTcpConnection does if you call
g_tcp_connection_set_graceful_disconnect(). But of course, this
only works if the client will close its connection after the server
does.)

<function name="g_socket_condition_check">
<description>
Checks on the readiness of @socket to perform operations.
The operations specified in @condition are checked for and masked
against the currently-satisfied conditions on @socket. The result
is returned.

Note that on Windows, it is possible for an operation to return
%G_IO_ERROR_WOULD_BLOCK even immediately after
g_socket_condition_check() has claimed that the socket is ready for
writing. Rather than calling g_socket_condition_check() and then
writing to the socket if it succeeds, it is generally better to
simply try writing to the socket right away, and try again later if
the initial attempt returns %G_IO_ERROR_WOULD_BLOCK.

It is meaningless to specify %G_IO_ERR or %G_IO_HUP in condition;
these conditions will always be set in the output if they are true.

This call never blocks.

<description>
Waits for up to @timeout_us microseconds for @condition to become true

If @cancellable is cancelled before the condition is met, or if
@timeout_us (or the socket's #GSocket:timeout) is reached before the
condition is met, then %FALSE is returned and @error, if non-%NULL,
is set to the appropriate value (%G_IO_ERROR_CANCELLED or
%G_IO_ERROR_TIMED_OUT).

If you don't want a timeout, use g_socket_condition_wait().
(Alternatively, you can pass -1 for @timeout_us.)

Note that although @timeout_us is in microseconds for consistency with
other GLib APIs, this function actually only has millisecond
resolution, and the behavior is undefined if @timeout_us is not an
exact number of milliseconds.

<description>
Connect the socket to the specified remote address.

For connection oriented socket this generally means we attempt to make
a connection to the @address. For a connection-less socket it sets
the default address for g_socket_send() and discards all incoming datagrams
from other sources.

Generally connection oriented sockets can only connect once, but
connection-less sockets can connect multiple times to change the
default address.

If the connect call needs to do network I/O it will block, unless
non-blocking I/O is enabled. Then %G_IO_ERROR_PENDING is returned
and the user can be notified of the connection finishing by waiting
for the G_IO_OUT condition. The result of the connection must then be
checked with g_socket_check_connect_result().

<description>
Creates a #GSource that can be attached to a %GMainContext to monitor
for the availability of the specified @condition on the socket. The #GSource
keeps a reference to the @socket.

The callback on the source is of the #GSocketSourceFunc type.

It is meaningless to specify %G_IO_ERR or %G_IO_HUP in @condition;
these conditions will always be reported output if they are true.

@cancellable if not %NULL can be used to cancel the source, which will
cause the source to trigger, reporting the current condition (which
is likely 0 unless cancellation happened at the same time as a
condition change). You can check for this in the callback using
g_cancellable_is_cancelled().

If @socket has a timeout set, and it is reached before @condition
occurs, the source will then trigger anyway, reporting %G_IO_IN or
%G_IO_OUT depending on @condition. However, @socket will have been
marked as having had a timeout, and so the next #GSocket I/O method
you call will then fail with a %G_IO_ERROR_TIMED_OUT.

Note that on Windows, this function is rather inefficient in the
UDP case, and so if you know any plausible upper bound on the size
of the incoming packet, it is better to just do a
g_socket_receive() with a buffer of that size, rather than calling
g_socket_get_available_bytes() first and then doing a receive of
exactly the right size.

<function name="g_socket_listener_add_address">
<description>
Creates a socket of type @type and protocol @protocol, binds
it to @address and adds it to the set of sockets we're accepting
sockets from.

Note that adding an IPv6 address, depending on the platform,
may or may not result in a listener that also accepts IPv4
connections.  For more deterministic behavior, see
g_socket_listener_add_inet_port().

@source_object will be passed out in the various calls
to accept to identify this particular source, which is
useful if you're listening on multiple addresses and do
different things depending on what address is connected to.

If successful and @effective_address is non-%NULL then it will
be set to the address that the binding actually occurred at.  This
is helpful for determining the port number that was used for when
requesting a binding to port 0 (ie: &quot;any port&quot;).  This address, if
requested, belongs to the caller and must be freed.

Call g_socket_listener_close() to stop listening on @address; this will not
be done automatically when you drop your final reference to @listener, as
references may be held internally.

Receive data (up to @size bytes) from a socket. This is mainly used by

For %G_SOCKET_TYPE_DATAGRAM and %G_SOCKET_TYPE_SEQPACKET sockets,
g_socket_receive() will always read either 0 or 1 complete messages from

the data beyond @size bytes will be discarded, without any explicit

For %G_SOCKET_TYPE_STREAM sockets, g_socket_receive() can return any
number of bytes, up to @size. If more than @size bytes have been

g_socket_receive().

If the socket is in blocking mode the call will block until there

<function name="g_socket_receive_message">
<description>
Receive data from a socket.  For receiving multiple messages, see
g_socket_receive_messages(); for easier use, see
g_socket_receive() and g_socket_receive_from().

If @address is non-%NULL then @address will be set equal to the
source address of the received packet.
@address is owned by the caller.

@vector must point to an array of #GInputVector structs and
@num_vectors must be the length of this array.  These structs
describe the buffers that received data will be scattered into.
If @num_vectors is -1, then @vectors is assumed to be terminated
by a #GInputVector with a %NULL buffer pointer.

As a special case, if @num_vectors is 0 (in which case, @vectors
may of course be %NULL), then a single byte is received and
discarded. This is to facilitate the common practice of sending a
single '\0' byte for the purposes of transferring ancillary data.

@messages, if non-%NULL, will be set to point to a newly-allocated
array of #GSocketControlMessage instances or %NULL if no such
messages was received. These correspond to the control messages
received from the kernel, one #GSocketControlMessage per message
from the kernel. This array is %NULL-terminated and must be freed
by the caller using g_free() after calling g_object_unref() on each
element. If @messages is %NULL, any control messages received will
be discarded.

@num_messages, if non-%NULL, will be set to the number of control
messages received.

If both @messages and @num_messages are non-%NULL, then
@num_messages gives the number of #GSocketControlMessage instances
in @messages (ie: not including the %NULL terminator).

@flags is an in/out parameter. The commonly available arguments
for this are available in the #GSocketMsgFlags enum, but the
values there are the same as the system values, and the flags
are passed in as-is, so you can pass in system-specific flags too
(and g_socket_receive_message() may pass system-specific flags out).
Flags passed in to the parameter affect the receive operation; flags returned
out of it are relevant to the specific returned message.

As with g_socket_receive(), data may be discarded if @socket is
%G_SOCKET_TYPE_DATAGRAM or %G_SOCKET_TYPE_SEQPACKET and you do not
provide enough buffer space to read a complete message. You can pass
%G_SOCKET_MSG_PEEK in @flags to peek at the current message without
removing it from the receive queue, but there is no portable way to find
out the length of the message other than by reading it into a
sufficiently-large buffer.

If the socket is in blocking mode the call will block until there
is some data to receive, the connection is closed, or there is an
error. If there is no data available and the socket is in
non-blocking mode, a %G_IO_ERROR_WOULD_BLOCK error will be
returned. To be notified when data is available, wait for the
%G_IO_IN condition.

On error -1 is returned and @error is set accordingly.

<function name="g_socket_receive_messages">
<description>
Receive multiple data messages from @socket in one go.  This is the most
complicated and fully-featured version of this call. For easier use, see
g_socket_receive(), g_socket_receive_from(), and g_socket_receive_message().

@messages must point to an array of #GInputMessage structs and
@num_messages must be the length of this array. Each #GInputMessage
contains a pointer to an array of #GInputVector structs describing the
buffers that the data received in each message will be written to. Using
multiple #GInputVectors is more memory-efficient than manually copying data
out of a single buffer to multiple sources, and more system-call-efficient
than making multiple calls to g_socket_receive(), such as in scenarios where
a lot of data packets need to be received (e.g. high-bandwidth video
streaming over RTP/UDP).

@flags modify how all messages are received. The commonly available
arguments for this are available in the #GSocketMsgFlags enum, but the
values there are the same as the system values, and the flags
are passed in as-is, so you can pass in system-specific flags too. These
flags affect the overall receive operation. Flags affecting individual
messages are returned in #GInputMessage.flags.

The other members of #GInputMessage are treated as described in its
documentation.

If #GSocket:blocking is %TRUE the call will block until @num_messages have
been received, or the end of the stream is reached.

If #GSocket:blocking is %FALSE the call will return up to @num_messages
without blocking, or %G_IO_ERROR_WOULD_BLOCK if no messages are queued in the
operating system to be received.

In blocking mode, if #GSocket:timeout is positive and is reached before any
messages are received, %G_IO_ERROR_TIMED_OUT is returned, otherwise up to
@num_messages are returned. (Note: This is effectively the
behaviour of `MSG_WAITFORONE` with recvmmsg().)

To be notified when messages are available, wait for the
%G_IO_IN condition. Note though that you may still receive
%G_IO_ERROR_WOULD_BLOCK from g_socket_receive_messages() even if you were
previously notified of a %G_IO_IN condition.

If the remote peer closes the connection, any messages queued in the
operating system will be returned, and subsequent calls to
g_socket_receive_messages() will return 0 (with no error set).

On error -1 is returned and @error is set accordingly. An error will only
be returned if zero messages could be received; otherwise the number of
messages successfully received before the error will be returned.

If @address is %NULL then the message is sent to the default receiver
(set by g_socket_connect()).

@vectors must point to an array of #GOutputVector structs and
@num_vectors must be the length of this array. (If @num_vectors is -1,
then @vectors is assumed to be terminated by a #GOutputVector with a
%NULL buffer pointer.) The #GOutputVector structs describe the buffers
that the sent data will be gathered from. Using multiple
#GOutputVectors is more memory-efficient than manually copying
data from multiple sources into a single buffer, and more
network-efficient than making multiple calls to g_socket_send().

@messages, if non-%NULL, is taken to point to an array of @num_messages
#GSocketControlMessage instances. These correspond to the control

<function name="g_socket_send_messages">
<description>
Send multiple data messages from @socket in one go.  This is the most
complicated and fully-featured version of this call. For easier use, see
g_socket_send(), g_socket_send_to(), and g_socket_send_message().

@messages must point to an array of #GOutputMessage structs and
@num_messages must be the length of this array. Each #GOutputMessage
contains an address to send the data to, and a pointer to an array of
#GOutputVector structs to describe the buffers that the data to be sent
for each message will be gathered from. Using multiple #GOutputVectors is
more memory-efficient than manually copying data from multiple sources
into a single buffer, and more network-efficient than making multiple
calls to g_socket_send(). Sending multiple messages in one go avoids the
overhead of making a lot of syscalls in scenarios where a lot of data
packets need to be sent (e.g. high-bandwidth video streaming over RTP/UDP),
or where the same data needs to be sent to multiple recipients.

@flags modify how the message is sent. The commonly available arguments
for this are available in the #GSocketMsgFlags enum, but the
values there are the same as the system values, and the flags
are passed in as-is, so you can pass in system-specific flags too.

If the socket is in blocking mode the call will block until there is
space for all the data in the socket queue. If there is no space available
and the socket is in non-blocking mode a %G_IO_ERROR_WOULD_BLOCK error
will be returned if no data was written at all, otherwise the number of
messages sent will be returned. To be notified when space is available,
wait for the %G_IO_OUT condition. Note though that you may still receive
%G_IO_ERROR_WOULD_BLOCK from g_socket_send() even if you were previously
notified of a %G_IO_OUT condition. (On Windows in particular, this is
very common due to the way the underlying APIs work.)

On error -1 is returned and @error is set accordingly. An error will only
be returned if zero messages could be sent; otherwise the number of messages
successfully sent before the error will be returned.

This option is only functional on certain kinds of sockets. (Notably,
%G_SOCKET_PROTOCOL_TCP sockets.)

The exact time between pings is system- and protocol-dependent, but will
normally be at least two hours. Most commonly, you would set this flag
on a server socket if you want to allow clients to remain idle for long
periods of time, but also want to ensure that connections are eventually
garbage-collected if clients crash or become unreachable.

created with g_socket_create_source() will trigger after
@timeout seconds of inactivity, with the requested condition
set, at which point calling g_socket_receive(), g_socket_send(),
g_socket_check_connect_result(), etc, will fail with
%G_IO_ERROR_TIMED_OUT.

If @timeout is 0 (the default), operations will never time out

<function name="g_subprocess_communicate">
<description>
Communicate with the subprocess until it terminates, and all input
and output has been completed.

If @stdin_buf is given, the subprocess must have been created with
%G_SUBPROCESS_FLAGS_STDIN_PIPE.  The given data is fed to the
stdin of the subprocess and the pipe is closed (ie: EOF).

At the same time (as not to cause blocking when dealing with large
amounts of data), if %G_SUBPROCESS_FLAGS_STDOUT_PIPE or
%G_SUBPROCESS_FLAGS_STDERR_PIPE were used, reads from those
streams.  The data that was read is returned in @stdout and/or
the @stderr.

If the subprocess was created with %G_SUBPROCESS_FLAGS_STDOUT_PIPE,
@stdout_buf will contain the data read from stdout.  Otherwise, for
subprocesses not created with %G_SUBPROCESS_FLAGS_STDOUT_PIPE,
@stdout_buf will be set to %NULL.  Similar provisions apply to
@stderr_buf and %G_SUBPROCESS_FLAGS_STDERR_PIPE.

As usual, any output variable may be given as %NULL to ignore it.

If you desire the stdout and stderr data to be interleaved, create
the subprocess with %G_SUBPROCESS_FLAGS_STDOUT_PIPE and
%G_SUBPROCESS_FLAGS_STDERR_MERGE.  The merged result will be returned
in @stdout_buf and @stderr_buf will be set to %NULL.

In case of any error (including cancellation), %FALSE will be
returned with @error set.  Some or all of the stdin data may have
been written.  Any stdout or stderr data that has been read will be
discarded. None of the out variables (aside from @error) will have
been set to anything in particular and should not be inspected.

In the case that %TRUE is returned, the subprocess has exited and the
exit status inspection APIs (eg: g_subprocess_get_if_exited(),
g_subprocess_get_exit_status()) may be used.

You should not attempt to use any of the subprocess pipes after
starting this function, since they may be left in strange states,
even if the operation was cancelled.  You should especially not
attempt to interact with the pipes while the operation is in progress
(either from another thread or if using the asynchronous version).

Transfer an arbitrary file descriptor from parent process to the

By default, all file descriptors from the parent will be closed.
This function allows you to create (for example) a custom `pipe()` or
`socketpair()` before launching the process, and choose the target
descriptor in the child.

An example use case is GNUPG, which has a command line argument
`--passphrase-fd` providing a file descriptor number where it expects
the passphrase to be written.

Synchronously wait for the subprocess to terminate.

After the process terminates you can query its exit status with

This function does not fail in the case of the subprocess having
abnormal termination.  See g_subprocess_wait_check() for that.

Cancelling @cancellable doesn't kill the subprocess.  Call
g_subprocess_force_exit() if it is desirable.

By default, if @cancellable is cancelled, then the return value of

<function name="g_task_set_name">
<description>
Sets @task’s name, used in debugging and profiling. The name defaults to
%NULL.

The task name should describe in a human readable way what the task does.
For example, ‘Open file’ or ‘Connect to network host’. It is used to set the
name of the #GSource used for idle completion of the task.

This function may only be called before the @task is first used in a thread
other than the one it was constructed in. It is called automatically by
g_task_set_source_tag() if not called already.

<function name="g_task_set_return_on_cancel">
<description>
Sets or clears @task's return-on-cancel flag. This is only
meaningful for tasks run via g_task_run_in_thread() or
g_task_run_in_thread_sync().

If @return_on_cancel is %TRUE, then cancelling @task's
#GCancellable will immediately cause it to return, as though the
task's #GTaskThreadFunc had called
g_task_return_error_if_cancelled() and then returned.

This allows you to create a cancellable wrapper around an
uninterruptible function. The #GTaskThreadFunc just needs to be
careful that it does not modify any externally-visible state after
it has been cancelled. To do that, the thread should call
g_task_set_return_on_cancel() again to (atomically) set
return-on-cancel %FALSE before making externally-visible changes;
if the task gets cancelled before the return-on-cancel flag could
be changed, g_task_set_return_on_cancel() will indicate this by
returning %FALSE.

You can disable and re-enable this flag multiple times if you wish.
If the task's #GCancellable is cancelled while return-on-cancel is
%FALSE, then calling g_task_set_return_on_cancel() to set it %TRUE
again will cause the task to be cancelled at that point.

If the task's #GCancellable is already cancelled before you call
g_task_run_in_thread()/g_task_run_in_thread_sync(), then the
#GTaskThreadFunc will still be run (for consistency), but the task
will also be completed right away.

<function name="g_task_set_source_tag">
<description>
Sets @task's source tag.

You can use this to tag a task return
value with a particular pointer (usually a pointer to the function
doing the tagging) and then later check it using
g_task_get_source_tag() (or g_async_result_is_tagged()) in the
task's &quot;finish&quot; function, to figure out if the response came from a
particular place.

A macro wrapper around this function will automatically set the
task’s name to the string form of @source_tag if it’s not already
set, for convenience.

Creates a #GTlsCertificate from the PEM-encoded data in @cert_file
and @key_file. The returned certificate will be the first certificate
found in @cert_file. As of GLib 2.44, if @cert_file contains more
certificates it will try to load a certificate chain. All
certificates will be verified in the order found (top-level
certificate should be the last one in the file) and the
#GTlsCertificate:issuer property of each certificate will be set

chain cannot be verified, the first certificate in the file will
still be returned.

If either file cannot be read or parsed, the function will return
%NULL and set @error. Otherwise, this behaves like

Creates a #GTlsCertificate from a
[PKCS \#11](https://docs.oasis-open.org/pkcs11/pkcs11-base/v3.0/os/pkcs11-base-v3.0-os.html) URI.

An example @pkcs11_uri would be `pkcs11:model=Model;manufacturer=Manufacture;serial=1;token=My%20Client%20Certificate;id=%01`

Where the token’s layout is:

|[
Object 0:
URL: pkcs11:model=Model;manufacturer=Manufacture;serial=1;token=My%20Client%20Certificate;id=%01;object=private%20key;type=private
Type: Private key (RSA-2048)

Object 1:

In this case the certificate and private key would both be detected and used as expected.
@pkcs_uri may also just reference an X.509 certificate object and then optionally
@private_key_pkcs11_uri allows using a private key exposed under a different URI.

<function name="g_tls_certificate_verify">
<description>
This verifies @cert and returns a set of #GTlsCertificateFlags
indicating any problems found with it. This can be used to verify a
certificate outside the context of making a connection, or to
check a certificate against a CA that is not part of the system
CA database.

If @cert is valid, %G_TLS_CERTIFICATE_NO_FLAGS is returned.

If @identity is not %NULL, @cert's name(s) will be compared against
it, and %G_TLS_CERTIFICATE_BAD_IDENTITY will be set in the return
value if it does not match. If @identity is %NULL, that bit will
never be set in the return value.

If @trusted_ca is not %NULL, then @cert (or one of the certificates
in its chain) must be signed by it, or else
%G_TLS_CERTIFICATE_UNKNOWN_CA will be set in the return value. If
@trusted_ca is %NULL, that bit will never be set in the return
value.

GLib guarantees that if certificate verification fails, at least one
error will be set in the return value, but it does not guarantee
that all possible errors will be set. Accordingly, you may not safely
decide to ignore any particular type of error. For example, it would
be incorrect to mask %G_TLS_CERTIFICATE_EXPIRED if you want to allow
expired certificates, because this could potentially be the only
error flag set even if other problems exist with the certificate.

Because TLS session context is not used, #GTlsCertificate may not
perform as many checks on the certificates as #GTlsConnection would.
For example, certificate constraints may not be honored, and
revocation checks may not be performed. The best way to verify TLS
certificates used by a TLS connection is to let #GTlsConnection
handle the verification.

<function name="g_tls_client_connection_copy_session_state">
<description>
Possibly copies session state from one connection to another, for use
in TLS session resumption. This is not normally needed, but may be
used when the same session needs to be used between different
endpoints, as is required by some protocols, such as FTP over TLS.
@source should have already completed a handshake and, since TLS 1.3,
it should have been used to read data at least once. @conn should not
have completed a handshake.

It is not possible to know whether a call to this function will
actually do anything. Because session resumption is normally used
only for performance benefit, the TLS backend might not implement
this function. Even if implemented, it may not actually succeed in
allowing @conn to resume @source's TLS session, because the server
may not have sent a session resumption token to @source, or it may
refuse to accept the token from @conn. There is no way to know
whether a call to this function is actually successful.

Using this function is not required to benefit from session
resumption. If the TLS backend supports session resumption, the
session will be resumed automatically if it is possible to do so
without weakening the privacy guarantees normally provided by TLS,
without need to call this function. For example, with TLS 1.3,
a session ticket will be automatically copied from any
#GTlsClientConnection that has previously received session tickets
from the server, provided a ticket is available that has not
previously been used for session resumption, since session ticket
reuse would be a privacy weakness. Using this function causes the
ticket to be copied without regard for privacy considerations.

<description>
Attempts a TLS handshake on @conn.

On the client side, it is never necessary to call this method;
although the connection needs to perform a handshake after
connecting (or after sending a &quot;STARTTLS&quot;-type command),
#GTlsConnection will handle this for you automatically when you try
to send or receive data on the connection. You can call
g_tls_connection_handshake() manually if you want to know whether
the initial handshake succeeded or failed (as opposed to just
immediately trying to use @conn to read or write, in which case,
if it fails, it may not be possible to tell if it failed before or
after completing the handshake), but beware that servers may reject
client authentication after the handshake has completed, so a
successful handshake does not indicate the connection will be usable.

Likewise, on the server side, although a handshake is necessary at
the beginning of the communication, you do not need to call this
function explicitly unless you want clearer error reporting.

Previously, calling g_tls_connection_handshake() after the initial
handshake would trigger a rehandshake; however, this usage was
deprecated in GLib 2.60 because rehandshaking was removed from the
TLS protocol in TLS 1.3. Since GLib 2.64, calling this function after
the initial handshake will no longer do anything.

When using a #GTlsConnection created by #GSocketClient, the
#GSocketClient performs the initial handshake, so calling this

of @protocols will disable ALPN negotiation.

<function name="g_tls_connection_set_certificate">
<description>
This sets the certificate that @conn will present to its peer
during the TLS handshake. For a #GTlsServerConnection, it is
mandatory to set this, and that will normally be done at construct
time.

For a #GTlsClientConnection, this is optional. If a handshake fails
with %G_TLS_ERROR_CERTIFICATE_REQUIRED, that means that the server
requires a certificate, and if you try connecting again, you should
call this method first. You can call
g_tls_client_connection_get_accepted_cas() on the failed connection
to get a list of Certificate Authorities that the server will
accept certificates from.

(It is also possible that a server will allow the connection with
or without a certificate; in that case, if you don't provide a
certificate, you can tell that the server requested one by the fact
that g_tls_client_connection_get_accepted_cas() will return
non-%NULL.)

<function name="g_tls_connection_set_require_close_notify">
<description>
Sets whether or not @conn expects a proper TLS close notification
before the connection is closed. If this is %TRUE (the default),
then @conn will expect to receive a TLS close notification from its
peer before the connection is closed, and will return a
%G_TLS_ERROR_EOF error if the connection is closed without proper
notification (since this may indicate a network error, or
man-in-the-middle attack).

In some protocols, the application will know whether or not the
connection was closed cleanly based on application-level data
(because the application-level data includes a length field, or is
somehow self-delimiting); in this case, the close notify is
redundant and sometimes omitted. (TLS 1.1 explicitly allows this;
in TLS 1.0 it is technically an error, but often done anyway.) You
can use g_tls_connection_set_require_close_notify() to tell @conn
to allow an &quot;unannounced&quot; connection close, in which case the close
will show up as a 0-length read, as in a non-TLS
#GSocketConnection, and it is up to the application to check that
the data has been fully received.

Note that this only affects the behavior when the peer closes the
connection; when the application calls g_io_stream_close() itself
on @conn, this will send a close notification regardless of the
setting of this property. If you explicitly want to do an unclean
close, you can close @conn's #GTlsConnection:base-io-stream rather
than closing @conn itself, but note that this may only be done when no other
operations are pending on @conn or the base I/O stream.

[RFC 4158](https://datatracker.ietf.org/doc/html/rfc4158) explains
why an issuer certificate cannot be naively assumed to be part of the
the certification path (though GLib's TLS backends may not follow the
path building strategies outlined in this RFC). Due to the complexity
of certification path building, GLib does not provide any way to know
which certification path will actually be used when verifying a TLS
certificate. Accordingly, this function cannot be used to make
security-related decisions. Only GLib itself should make security
decisions about TLS certificates.

<function name="g_tls_database_verify_chain">
<description>
Determines the validity of a certificate chain, outside the context
of a TLS session.

@chain is a chain of #GTlsCertificate objects each pointing to the next
certificate in the chain by its #GTlsCertificate:issuer property.

@purpose describes the purpose (or usage) for which the certificate
is being used. Typically @purpose will be set to %G_TLS_DATABASE_PURPOSE_AUTHENTICATE_SERVER
which means that the certificate is being used to authenticate a server
(and we are acting as the client).

The @identity is used to ensure the server certificate is valid for
the expected peer identity. If the identity does not match the
certificate, %G_TLS_CERTIFICATE_BAD_IDENTITY will be set in the
return value. If @identity is %NULL, that bit will never be set in
the return value. The peer identity may also be used to check for
pinned certificates (trust exceptions) in the database. These may
override the normal verification process on a host-by-host basis.

Currently there are no @flags, and %G_TLS_DATABASE_VERIFY_NONE should be
used.

If @chain is found to be valid, then the return value will be 0. If
@chain is found to be invalid, then the return value will indicate at
least one problem found. If the function is unable to determine
whether @chain is valid (for example, because @cancellable is
triggered before it completes) then the return value will be
%G_TLS_CERTIFICATE_GENERIC_ERROR and @error will be set accordingly.
@error is not set when @chain is successfully analyzed but found to
be invalid.

GLib guarantees that if certificate verification fails, at least one
error will be set in the return value, but it does not guarantee
that all possible errors will be set. Accordingly, you may not safely
decide to ignore any particular type of error. For example, it would
be incorrect to mask %G_TLS_CERTIFICATE_EXPIRED if you want to allow
expired certificates, because this could potentially be the only
error flag set even if other problems exist with the certificate.

Prior to GLib 2.48, GLib's default TLS backend modified @chain to
represent the certification path built by #GTlsDatabase during
certificate verification by adjusting the #GTlsCertificate:issuer
property of each certificate in @chain. Since GLib 2.48, this no
longer occurs, so you cannot rely on #GTlsCertificate:issuer to
represent the actual certification path used during certificate
verification.

Because TLS session context is not used, #GTlsDatabase may not
perform as many checks on the certificates as #GTlsConnection would.
For example, certificate constraints may not be honored, and
revocation checks may not be performed. The best way to verify TLS
certificates used by a TLS connection is to let #GTlsConnection
handle the verification.

The TLS backend may attempt to look up and add missing certificates
to the chain. This may involve HTTP requests to download missing
certificates.

This function can block. Use g_tls_database_verify_chain_async() to
perform the verification operation asynchronously.

If @type is %G_UNIX_SOCKET_ADDRESS_PATH, this is equivalent to
calling g_unix_socket_address_new().

If @type is %G_UNIX_SOCKET_ADDRESS_ANONYMOUS, @path and @path_len will be
ignored.

If @path_type is %G_UNIX_SOCKET_ADDRESS_ABSTRACT, then @path_len
bytes of @path will be copied to the socket's path, and only those
bytes will be considered part of the name. (If @path_len is -1,
then @path is assumed to be NUL-terminated.) For example, if @path
was &quot;test&quot;, then calling g_socket_address_get_native_size() on the
returned socket would return 7 (2 bytes of overhead, 1 byte for the
abstract-socket indicator byte, and 4 bytes for the name &quot;test&quot;).

If @path_type is %G_UNIX_SOCKET_ADDRESS_ABSTRACT_PADDED, then
@path_len bytes of @path will be copied to the socket's path, the
rest of the path will be padded with 0 bytes, and the entire
zero-padded buffer will be considered the name. (As above, if
@path_len is -1, then @path is assumed to be NUL-terminated.) In
this case, g_socket_address_get_native_size() will always return
the full size of a `struct sockaddr_un`, although
g_unix_socket_address_get_path_len() will still return just the
length of @path.

%G_UNIX_SOCKET_ADDRESS_ABSTRACT is preferred over
%G_UNIX_SOCKET_ADDRESS_ABSTRACT_PADDED for new programs. Of course,
when connecting to a server created by another process, you must
use the appropriate type corresponding to how that process created
its listening socket.

opposed to desktop-wide as it happens with GVfs backends.

When a #GFile is requested with an URI containing @scheme (e.g. through
g_file_new_for_uri()), @uri_func will be called to allow a custom
constructor. The implementation of @uri_func should not be blocking, and
must not call g_vfs_register_uri_scheme() or g_vfs_unregister_uri_scheme().

When g_file_parse_name() is called with a parse name obtained from such file,
@parse_name_func will be called to allow the #GFile to be created again. In
that case, it's responsibility of @parse_name_func to make sure the parse
name matches what the custom #GFile implementation returned when
g_file_get_parse_name() was previously called. The implementation of
@parse_name_func should not be blocking, and must not call
g_vfs_register_uri_scheme() or g_vfs_unregister_uri_scheme().

It's an error to call this function twice with the same scheme. To unregister
a custom URI scheme, use g_vfs_unregister_uri_scheme().

<function name="g_volume_monitor_adopt_orphan_mount">
<description>
This function should be called by any #GVolumeMonitor
implementation when a new #GMount object is created that is not
associated with a #GVolume object. It must be called just before
emitting the @mount_added signal.

If the return value is not %NULL, the caller must associate the
returned #GVolume object with the #GMount. This involves returning
it in its g_mount_get_volume() implementation. The caller must
also listen for the &quot;removed&quot; signal on the returned object
and give up its reference when handling that signal

Similarly, if implementing g_volume_monitor_adopt_orphan_mount(),
the implementor must take a reference to @mount and return it in
its g_volume_get_mount() implemented. Also, the implementor must
listen for the &quot;unmounted&quot; signal on @mount and give up its
reference upon handling that signal.

There are two main use cases for this function.

One is when implementing a user space file system driver that reads
blocks of a block device that is already represented by the native
volume monitor (for example a CD Audio file system driver). Such
a driver will generate its own #GMount object that needs to be
associated with the #GVolume object that represents the volume.

The other is for implementing a #GVolumeMonitor whose sole purpose
is to return #GVolume objects representing entries in the users
&quot;favorite servers&quot; list or similar.

Deprecated: 2.20: Instead of using this function, #GVolumeMonitor
implementations should instead create shadow mounts with the URI of
the mount they intend to adopt. See the proxy volume monitor in
gvfs for an example of this. Also see g_mount_is_shadowed(),
g_mount_shadow() and g_mount_unshadow() functions.

Puts @key under a watch.

When the key changes, an APC will be queued in the current thread. The APC

should do that; if you are not using it, see MSDN documentation for W32API
calls that put thread into alertable state). When it runs, it will
atomically switch an indicator in the @key. If a callback was specified,
it is invoked at that point. Subsequent calls to
g_win32_registry_key_has_changed() will return %TRUE, and the callback (if
it was specified) will not be invoked anymore.
Calling g_win32_registry_key_erase_change_indicator() will reset the indicator,
