<function name="g_file_enumerator_close_finish">
<description>
Finishes closing a file enumerator, started from g_file_enumerator_close_async().

If the file enumerator was already closed when g_file_enumerator_close_async() 
was called, then this function will throw a Gio::Error with CLOSED, and 
return %FALSE. If the file enumerator had pending operation when the close 
operation was started, then this function will throw a Gio::Error with PENDING, and
return %FALSE.  The operation may have been 
cancelled by triggering the cancellable object from another thread. If the operation
was cancelled, a Gio::Error with CANCELLED will be thrown, and %FALSE will be 
returned.
</description>
</function>

<function name="g_file_append_to">
<description>
Gets an output stream for appending data to the file. If
the file doesn&apos;t already exist it is created.

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.

The operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, a Gio::Error will be thrown with CANCELLED. 

Some file systems don&apos;t allow all file names, and may
throw a Gio::Error with INVALID_FILENAME.
If the file is a directory a Gio::Error with IS_DIRECTORY will be
thrown. Other errors are possible too, and depend on what kind of
filesystem the file is on.

<function name="g_file_set_display_name">
<description>
Renames @file to the specified display name.

The display name is converted from UTF8 to the correct encoding for the target
filesystem if possible and the @file is renamed to this.

If you want to implement a rename operation in the user interface the edit name
(#G_FILE_ATTRIBUTE_STANDARD_EDIT_NAME) should be used as the initial value in the rename
widget, and then the result after editing should be passed to g_file_set_display_name().

On success the resulting converted filename is returned.

The operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, a Gio::Error will be thrown with CANCELLED.

<function name="g_file_query_info">
<description>
Gets the requested information about specified @file. The result
is a #GFileInfo object that contains key-value attributes (such as 
the type or size of the file).

The @attribute value is a string that specifies the file attributes that
should be gathered. It is not an error if it&apos;s not possible to read a particular
requested attribute from a file - it just won&apos;t be set. @attribute should
be a comma-separated list of attribute 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.

The operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, a Gio::Error will be thrown with CANCELLED. 

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, a Gio::Error with NOT_FOUND will be thrown.
Other errors are possible too, and depend on what kind of filesystem the file is on.

<function name="g_input_stream_skip">
<description>
Tries to skip @count bytes from the stream. Will block during the operation.

This is identical to g_input_stream_read(), from a behaviour standpoint,
but the bytes that are skipped are not returned to the user. Some
streams have an implementation that is more efficient than reading the data.

This function is optional for inherited classes, as the default implementation
emulates it using read.

The operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, a Gio::Error will be thrown with CANCELLED. If an
operation was partially finished when the operation was cancelled the
partial result will be returned, without an error.

<description>
Sends @file to the &quot;Trashcan&quot;, if possible. This is similar to
deleting it, but the user can recover it before emptying the trashcan.
Not all file systems support trashing, so this call can throw a Gio::Error with 
 NOT_SUPPORTED.

<function name="g_file_set_attributes_from_info">
<description>
Tries to set all attributes in the #GFileInfo on the target values, 
not stopping on the first error.

If there is any error during this operation then @error will be set to
the first error. Error on particular fields are flagged by setting 
the &quot;status&quot; field in the attribute value to 
%G_FILE_ATTRIBUTE_STATUS_ERROR_SETTING, which means you can also detect
further errors.

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

Once the stream is closed, all other operations will throw a Gio::Error with 
CLOSED. Closing a stream multiple times will not cause an error to be 
thrown.

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 throw a Gio::Error with 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.

The operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, a Gio::Error will be thrown with CANCELLED.
Cancelling a close will still leave the stream closed, but there some streams
can use a faster close that doesn&apos;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.

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).

The operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, a Gio::Error will be thrown with CANCELLED. 

If the file does not exist, a Gio::Error with NOT_FOUND will be thrown.
Other errors are possible too, and depend on what kind of filesystem the file is on.

<function name="g_output_stream_write">
<description>
Tries to write @count bytes from @buffer into the stream. Will block
during the operation.

If count is zero returns zero and does nothing. A value of @count
larger than %G_MAXSSIZE will cause a Gio::Error with INVALID_ARGUMENT to be thrown.

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
storage in the stream. All writes either block until at least one byte
is written, so zero is never returned (unless @count is zero).

The operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, a Gio::Error will be thrown with CANCELLED. If an
operation was partially finished when the operation was cancelled the
partial result will be returned, without an error.

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

Note that in many cases it is racy to first check for file existence
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&apos;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 File::create() which will either atomically create the file
or fail with a Gio::Error exception with EXISTS.

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&apos;t have to fool users that something is possible and then just show
and 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.
