 /**

- * @see_also: #GParamSpecObject, g_param_spec_object()
- * @title: The Base Object Type
+ * GBoxedFreeFunc:
+ * @boxed: The boxed structure to be freed.
  *
- * GObject is the fundamental type providing the common attributes and
- * methods for all object types in GTK+, Pango and other libraries
- * based on GObject.  The GObject class provides methods for object
- * construction and destruction, property access methods, and signal
- * support.  Signals are described in detail in <xref
- * linkend="gobject-Signals"/>.
- * <para id="floating-ref">
- * #GInitiallyUnowned is derived from #GObject. The only difference between
- * the two is that the initial reference of a #GInitiallyUnowned is flagged
- * as a <firstterm>floating</firstterm> reference.
- * This means that it is not specifically claimed to be "owned" by
- * any code portion. The main motivation for providing floating references is
- * C convenience. In particular, it allows code to be written as:
- * |[
- * container = create_container();
- * container_add_child (container, create_child());
- * ]|
- * If <function>container_add_child()</function> will g_object_ref_sink() the
- * passed in child, no reference of the newly created child is leaked.
- * Without floating references, <function>container_add_child()</function>
- * can only g_object_ref() the new child, so to implement this code without
- * reference leaks, it would have to be written as:
- * |[
- * Child *child;
- * container = create_container();
- * child = create_child();
- * container_add_child (container, child);
- * g_object_unref (child);
- * ]|
- * The floating reference can be converted into
- * an ordinary reference by calling g_object_ref_sink().
- * For already sunken objects (objects that don't have a floating reference
- * anymore), g_object_ref_sink() is equivalent to g_object_ref() and returns
- * a new reference.
- * Since floating references are useful almost exclusively for C convenience,
- * language bindings that provide automated reference and memory ownership
- * maintenance (such as smart pointers or garbage collection) therefore don't
- * need to expose floating references in their API.
- * </para>
- * Some object implementations may need to save an objects floating state
- * across certain code portions (an example is #GtkMenu), to achive this, the
- * following sequence can be used:
- * |[
- * // save floating state
- * gboolean was_floating = g_object_is_floating (object);
- * g_object_ref_sink (object);
- * // protected code portion
- * ...;
- * // restore floating state
- * if (was_floating)
- * g_object_force_floating (object);
- * g_obejct_unref (object); // release previously acquired reference
- * ]|
+ * This function is provided by the user and should free the boxed
+ * structure passed.

 /**

+ * Since derived classes are partially initialized through a memory copy

+ * @G_REGEX_MULTILINE: By default, GRegex treats the strings as consisting of a single line of characters (even if it actually contains newlines). The "start of line" metacharacter ("^") matches only at the start of the string, while the "end of line" metacharacter ("$") matches only at the end of the string, or before a terminating newline (unless #G_REGEX_DOLLAR_ENDONLY is set). When #G_REGEX_MULTILINE is set, the "start of line" and "end of line" constructs match immediately following or immediately before any newline in the string, respectively, as well as at the very start and end. This can be changed within a pattern by a "(?m)" option setting.
+ * @G_REGEX_DOTALL: A dot metacharater (".") in the pattern matches all characters, including newlines. Without it, newlines are excluded. This option can be changed within a pattern by a ("?s") option setting.
+ * @G_REGEX_EXTENDED: Whitespace data characters in the pattern are totally ignored except when escaped or inside a character class. Whitespace does not include the VT character (code 11). In addition, characters between an unescaped "#" outside a character class and the next newline character, inclusive, are also ignored. This can be changed within a pattern by a "(?x)" option setting.
+ * @G_REGEX_ANCHORED: The pattern is forced to be "anchored", that is, it is constrained to match only at the first matching point in the string that is being searched. This effect can also be achieved by appropriate constructs in the pattern itself such as the "^" metacharater.
+ * @G_REGEX_DOLLAR_ENDONLY: A dollar metacharacter ("$") in the pattern matches only at the end of the string. Without this option, a dollar also matches immediately before the final character if it is a newline (but not before any other newlines). This option is ignored if #G_REGEX_MULTILINE is set.

+ * @G_REGEX_DUPNAMES: Names used to identify capturing subpatterns need not be unique. This can be helpful for certain types of pattern when it is known that only one instance of the named subpattern can ever be matched.
+ * @G_REGEX_NEWLINE_CR: Usually any newline character is recognized, if this option is set, the only recognized newline character is '\r'.

+ * @value_free: Free any old contents that might be left in the data array of the passed in @value. No resources may remain allocated through the #GValue contents after this function returns. E.g. for our above string type: |[ // only free strings without a specific flag for static storage if (!(value->data[1].v_uint & G_VALUE_NOCOPY_CONTENTS)) g_free (value->data[0].v_pointer); ]|
+ * @value_copy: @dest_value is a #GValue with zero-filled data section and @src_value is a properly setup #GValue of same or derived type. The purpose of this function is to copy the contents of remain valid. String type example: |[ dest_value->data[0].v_pointer = g_strdup (src_value->data[0].v_pointer); ]|
+ * @value_peek_pointer: If the value contents fit into a pointer, such as objects or strings, return this pointer, so the caller can peek at the current contents. To extend on our above string example: |[ return value->data[0].v_pointer; ]|
+ * @collect_format: A string format describing how to collect the contents of this value bit-by-bit. Each character in the format represents an argument to be collected, and the characters themselves indicate the type of the argument. Currently supported arguments are: <variablelist> <varlistentry><term /><listitem><para> 'i' - Integers. passed as collect_values[].v_int. </para></listitem></varlistentry> <varlistentry><term /><listitem><para> 'l' - Longs. passed as collect_values[].v_long. </para></listitem></varlistentry> <varlistentry><term /><listitem><para> 'd' - Doubles. passed as collect_values[].v_double. </para></listitem></varlistentry> <varlistentry><term /><listitem><para> 'p' - Pointers. passed as collect_values[].v_pointer. </para></listitem></varlistentry> </variablelist> It should be noted that for variable argument list construction, ANSI C promotes every type smaller than an integer to an int, and floats to doubles. So for collection of short int or char, 'i' needs to be used, and for collection of floats 'd'.
+ * @collect_value: The collect_value() function is responsible for converting the values collected from a variable argument list into contents suitable for storage in a GValue. This function should setup does not allow %NULL pointers, it needs to either spew an error, or do an implicit conversion by storing an empty string. The @value passed in to this function has a zero-filled data array, so just like for value_init() it is guaranteed to not contain any old contents that might need freeing. and @collect_values is an array of unions #GTypeCValue with length @n_collect_values, containing the collected values according to @collect_format. It may contain the flag %G_VALUE_NOCOPY_CONTENTS indicating, that the collected value contents may be considered "static" for the duration of the @value lifetime. Thus an extra copy of the contents stored in @collect_values is not required for assignment to @value. For our above string example, we continue with: |[ if (!collect_values[0].v_pointer) value->data[0].v_pointer = g_strdup (""); else if (collect_flags & G_VALUE_NOCOPY_CONTENTS) { value->data[0].v_pointer = collect_values[0].v_pointer; // keep a flag for the value_free() implementation to not free this string value->data[1].v_uint = G_VALUE_NOCOPY_CONTENTS; } else value->data[0].v_pointer = g_strdup (collect_values[0].v_pointer); return NULL; ]| It should be noted, that it is generally a bad idea to follow the #G_VALUE_NOCOPY_CONTENTS hint for reference counted types. Due to reentrancy requirements and reference count assertions performed by the #GSignal code, reference counts should always be incremented for reference counted contents stored in the value->data array. To deviate from our string example for a moment, and taking a look at an exemplary implementation for collect_value() of #GObject: |[ if (collect_values[0].v_pointer) { GObject *object = G_OBJECT (collect_values[0].v_pointer); // never honour G_VALUE_NOCOPY_CONTENTS for ref-counted types value->data[0].v_pointer = g_object_ref (object); return NULL; } else return g_strdup_printf ("Object passed as invalid NULL pointer"); } ]| The reference count for valid objects is always incremented, regardless of @collect_flags. For invalid objects, the example returns a newly allocated string without altering @value. Upon success, collect_value() needs to return %NULL. If, however, an error condition occurred, collect_value() may spew an error by returning a newly allocated non-%NULL string, giving a suitable description of the error condition. The calling code makes no assumptions about the @value contents being valid upon error returns, @value is simply thrown away without further freeing. As such, it is a good idea to not allocate #GValue contents, prior to returning an error, however, collect_values() is not obliged to return a correctly setup @value for error returns, simply because any non-%NULL return is considered a fatal condition so further program behaviour is undefined.
+ * @lcopy_format: Format description of the arguments to collect for @lcopy_value, analogous to @collect_format. Usually, @lcopy_format string consists only of 'p's to provide lcopy_value() with pointers to storage locations.

  *
- * #GTypeModule provides a simple implementation of the #GTypePlugin
- * interface. The model of #GTypeModule is a dynamically loaded module
- * which implements some number of types and interface
- * implementations. When the module is loaded, it registers its types
- * and interfaces using g_type_module_register_type() and
- * g_type_module_add_interface().  As long as any instances of these
- * types and interface implementations are in use, the module is kept
- * loaded. When the types and interfaces are gone, the module may be
- * unloaded. If the types and interfaces become used again, the module
- * will be reloaded. Note that the last unref can not happen in module
- * code, since that would lead to the caller's code being unloaded before
- * g_object_unref() returns to it.
- * Keeping track of whether the module should be loaded or not is done by
- * using a use count - it starts at zero, and whenever it is greater than
- * zero, the module is loaded. The use count is maintained internally by
- * the type system, but also can be explicitly controlled by
- * g_type_module_use() and g_type_module_unuse(). Typically, when loading
- * a module for the first type, g_type_module_use() will be used to load
- * it so that it can initialize its types. At some later point, when the
- * module no longer needs to be loaded except for the type
- * implementations it contains, g_type_module_unuse() is called.
- * #GTypeModule does not actually provide any implementation of module
- * loading and unloading. To create a particular module type you must
- * derive from #GTypeModule and implement the load and unload functions
- * in #GTypeModuleClass.

+ * G_PRIORITY_DEFAULT_IDLE:
  *
- * The GObject type system supports dynamic loading of types. The
- * #GTypePlugin interface is used to handle the lifecycle of
- * dynamically loaded types.  It goes as follows:
- * <orderedlist>
- * <listitem><para>
- * The type is initially introduced (usually upon loading the module
- * the first time, or by your main application that knows what modules
- * introduces what types), like this:
- * |[
- * new_type_id = g_type_register_dynamic (parent_type_id,
- * "TypeName",
- * new_type_plugin,
- * type_flags);
- * ]|
- * where <literal>new_type_plugin</literal> is an implementation of the
- * #GTypePlugin interface.
- * </para></listitem>
- * <listitem><para>
- * The type's implementation is referenced, e.g. through
- * g_type_class_ref() or through g_type_create_instance() (this is
- * being called by g_object_new()) or through one of the above done on
- * a type derived from <literal>new_type_id</literal>.
- * </para></listitem>
- * <listitem><para>
- * This causes the type system to load the type's implementation by calling
- * g_type_plugin_use() and g_type_plugin_complete_type_info() on
- * <literal>new_type_plugin</literal>.
- * </para></listitem>
- * <listitem><para>
- * At some point the type's implementation isn't required anymore, e.g. after
- * g_type_class_unref() or g_type_free_instance() (called when the reference
- * count of an instance drops to zero).
- * </para></listitem>
- * <listitem><para>
- * This causes the type system to throw away the information retrieved from
- * g_type_plugin_complete_type_info() and then it calls
- * g_type_plugin_unuse() on <literal>new_type_plugin</literal>.
- * </para></listitem>
- * <listitem><para>
- * Things may repeat from the second step.
- * </para></listitem>
- * </orderedlist>
- * So basically, you need to implement a #GTypePlugin type that
- * carries a use_count, once use_count goes from zero to one, you need
- * to load the implementation to successfully handle the upcoming
- * g_type_plugin_complete_type_info() call. Later, maybe after
- * succeeding use/unuse calls, once use_count drops to zero, you can
- * unload the implementation again. The type system makes sure to call
- * g_type_plugin_use() and g_type_plugin_complete_type_info() again
- * when the type is needed again.
- * #GTypeModule is an implementation of #GTypePlugin that already
- * implements most of this except for the actual module loading and
- * unloading. It even handles multiple registered types per module.
+ * Use this for default priority idle functions.
+ * In GLib this priority is used when adding idle functions with

- * SECTION:gtyp:
- * @short_description: The GLib Runtime type identification and management system
- *
- * The GType API is the foundation of the GObject system.  It provides the
- * facilities for registering and managing all fundamental data types,
- * user-defined object and interface types.  Before using any GType
- * or GObject functions, g_type_init() must be called to initialize the
- * type system.
- * For type creation and registration purposes, all types fall into one of
- * unloaded at run-time as dynamic types may be.  Static types are created
- * with g_type_register_static() that gets type specific information passed
- * in via a #GTypeInfo structure.
- * Dynamic types are created with g_type_register_dynamic() which takes a
- * #GTypePlugin structure instead. The remaining type information (the
- * #GTypeInfo structure) is retrieved during runtime through #GTypePlugin
- * and the g_type_plugin_*() API.
- * These registration functions are usually called only once from a
- * function whose only purpose is to return the type identifier for a
- * specific class.  Once the type (or class or interface) is registered,
- * it may be instantiated, inherited, or implemented depending on exactly
- * what sort of type it is.
- * There is also a third registration function for registering fundamental
- * types called g_type_register_fundamental() which requires both a #GTypeInfo
- * structure and a #GTypeFundamentalInfo structure but it is seldom used
- * since most fundamental types are predefined rather than user-defined.
- * A final word about type names.
- * Such an identifier needs to be at least three characters long. There is no
- * upper length limit. The first character needs to be a letter (a-z or A-Z)
- * or an underscore '_'. Subsequent characters can be letters, numbers or
- * any of '-_+'.
+ * G_TYPE_CHECK_INSTANCE_CAST:
+ * @instance: Location of a #GTypeInstance structure.
+ * @g_type: The type to be returned.
+ * @c_type: The corresponding C type of @g_type.
  *
- * Two categories: static or dynamic.  Static types are never loaded or
+ * Checks that @instance is an instance of the type identified by @g_type

 /**
- * SECTION:signal:
- * @short_description: A means for customization of object behaviour and a general purpose notification mechanism
- * @title: Signals
+ * G_TYPE_UCHAR:
  *
- * The basic concept of the signal system is that of the
- * <emphasis>emission</emphasis> of a signal. Signals are introduced
- * per-type and are identified through strings.  Signals introduced
- * for a parent type are available in derived types as well, so
- * basically they are a per-type facility that is inherited.  A signal
- * emission mainly involves invocation of a certain set of callbacks
- * in precisely defined manner. There are two main categories of such
- * callbacks, per-object
- * <footnote><para>Although signals can deal with any kind of instantiatable
- * type, i'm referring to those types as "object types" in the following,
- * simply because that is the context most users will encounter signals in.
- * </para></footnote>
- * ones and user provided ones.
- * The per-object callbacks are most often referred to as "object method
- * handler" or "default (signal) handler", while user provided callbacks are
- * usually just called "signal handler".
- * The object method handler is provided at signal creation time (this most
- * frequently happens at the end of an object class' creation), while user
- * provided handlers are frequently connected and disconnected to/from a certain
- * signal on certain object instances.
- * A signal emission consists of five stages, unless prematurely stopped:
- * <variablelist>
- * <varlistentry><term></term><listitem><para>
- * 1 - Invocation of the object method handler for %G_SIGNAL_RUN_FIRST signals
- * </para></listitem></varlistentry>
- * <varlistentry><term></term><listitem><para>
- * 2 - Invocation of normal user-provided signal handlers (<emphasis>after</emphasis> flag %FALSE)
- * </para></listitem></varlistentry>
- * <varlistentry><term></term><listitem><para>
- * 3 - Invocation of the object method handler for %G_SIGNAL_RUN_LAST signals
- * </para></listitem></varlistentry>
- * <varlistentry><term></term><listitem><para>
- * 4 - Invocation of user provided signal handlers, connected with an <emphasis>after</emphasis> flag of %TRUE
- * </para></listitem></varlistentry>
- * <varlistentry><term></term><listitem><para>
- * 5 - Invocation of the object method handler for %G_SIGNAL_RUN_CLEANUP signals
- * </para></listitem></varlistentry>
- * </variablelist>
- * The user-provided signal handlers are called in the order they were
- * connected in.
- * All handlers may prematurely stop a signal emission, and any number of
- * handlers may be connected, disconnected, blocked or unblocked during
- * a signal emission.
- * There are certain criteria for skipping user handlers in stages 2 and 4
- * of a signal emission.
- * First, user handlers may be <emphasis>blocked</emphasis>, blocked handlers are omitted
- * during callback invocation, to return from the "blocked" state, a
- * handler has to get unblocked exactly the same amount of times
- * it has been blocked before.
- * Second, upon emission of a %G_SIGNAL_DETAILED signal, an additional
- * "detail" argument passed in to g_signal_emit() has to match the detail
- * argument of the signal handler currently subject to invocation.
- * Specification of no detail argument for signal handlers (omission of the
- * detail part of the signal specification upon connection) serves as a
- * wildcard and matches any detail argument passed in to emission.

 /**
- * GTypeValueTable:
- * @value_init: Default initialize @values contents by poking values directly into the value->data array. The data array of the #GValue passed into this function was zero-filled with <function>memset()</function>, so no care has to be taken to free any old contents. E.g. for the implementation of a string value that may never be %NULL, the implementation might look like: |[ value->data[0].v_pointer = g_strdup (""); ]|
- * @value_free: Free any old contents that might be left in the data array of the passed in @value. No resources may remain allocated through the #GValue contents after this function returns. E.g. for our above string type: |[ // only free strings without a specific flag for static storage if (!(value->data[1].v_uint & G_VALUE_NOCOPY_CONTENTS)) g_free (value->data[0].v_pointer); ]|
- * @value_copy: @dest_value is a #GValue with zero-filled data section and @src_value is a properly setup #GValue of same or derived type. The purpose of this function is to copy the contents of remain valid. String type example: |[ dest_value->data[0].v_pointer = g_strdup (src_value->data[0].v_pointer); ]|
- * @value_peek_pointer: If the value contents fit into a pointer, such as objects or strings, return this pointer, so the caller can peek at the current contents. To extend on our above string example: |[ return value->data[0].v_pointer; ]|
- * @collect_format: A string format describing how to collect the contents of this value bit-by-bit. Each character in the format represents an argument to be collected, and the characters themselves indicate the type of the argument. Currently supported arguments are: <variablelist> <varlistentry><term /><listitem><para> 'i' - Integers. passed as collect_values[].v_int. </para></listitem></varlistentry> <varlistentry><term /><listitem><para> 'l' - Longs. passed as collect_values[].v_long. </para></listitem></varlistentry> <varlistentry><term /><listitem><para> 'd' - Doubles. passed as collect_values[].v_double. </para></listitem></varlistentry> <varlistentry><term /><listitem><para> 'p' - Pointers. passed as collect_values[].v_pointer. </para></listitem></varlistentry> </variablelist> It should be noted that for variable argument list construction, ANSI C promotes every type smaller than an integer to an int, and floats to doubles. So for collection of short int or char, 'i' needs to be used, and for collection of floats 'd'.
- * @collect_value: The collect_value() function is responsible for converting the values collected from a variable argument list into contents suitable for storage in a GValue. This function should setup does not allow %NULL pointers, it needs to either spew an error, or do an implicit conversion by storing an empty string. The @value passed in to this function has a zero-filled data array, so just like for value_init() it is guaranteed to not contain any old contents that might need freeing. and @collect_values is an array of unions #GTypeCValue with length @n_collect_values, containing the collected values according to @collect_format. It may contain the flag %G_VALUE_NOCOPY_CONTENTS indicating, that the collected value contents may be considered "static" for the duration of the @value lifetime. Thus an extra copy of the contents stored in @collect_values is not required for assignment to @value. For our above string example, we continue with: |[ if (!collect_values[0].v_pointer) value->data[0].v_pointer = g_strdup (""); else if (collect_flags & G_VALUE_NOCOPY_CONTENTS) { value->data[0].v_pointer = collect_values[0].v_pointer; // keep a flag for the value_free() implementation to not free this string value->data[1].v_uint = G_VALUE_NOCOPY_CONTENTS; } else value->data[0].v_pointer = g_strdup (collect_values[0].v_pointer); return NULL; ]| It should be noted, that it is generally a bad idea to follow the #G_VALUE_NOCOPY_CONTENTS hint for reference counted types. Due to reentrancy requirements and reference count assertions performed by the #GSignal code, reference counts should always be incremented for reference counted contents stored in the value->data array. To deviate from our string example for a moment, and taking a look at an exemplary implementation for collect_value() of #GObject: |[ if (collect_values[0].v_pointer) { GObject *object = G_OBJECT (collect_values[0].v_pointer); // never honour G_VALUE_NOCOPY_CONTENTS for ref-counted types value->data[0].v_pointer = g_object_ref (object); return NULL; } else return g_strdup_printf ("Object passed as invalid NULL pointer"); } ]| The reference count for valid objects is always incremented, regardless of @collect_flags. For invalid objects, the example returns a newly allocated string without altering @value. Upon success, collect_value() needs to return %NULL. If, however, an error condition occurred, collect_value() may spew an error by returning a newly allocated non-%NULL string, giving a suitable description of the error condition. The calling code makes no assumptions about the @value contents being valid upon error returns, @value is simply thrown away without further freeing. As such, it is a good idea to not allocate #GValue contents, prior to returning an error, however, collect_values() is not obliged to return a correctly setup @value for error returns, simply because any non-%NULL return is considered a fatal condition so further program behaviour is undefined.
- * @lcopy_format: Format description of the arguments to collect for @lcopy_value, analogous to @collect_format. Usually, @lcopy_format string consists only of 'p's to provide lcopy_value() with pointers to storage locations.
- * @lcopy_value: This function is responsible for storing the @value contents into arguments passed through a variable argument list which got collected into @collect_values according to @lcopy_format. and @collect_flags may contain %G_VALUE_NOCOPY_CONTENTS. In contrast to collect_value(), lcopy_value() is obliged to always properly support %G_VALUE_NOCOPY_CONTENTS. Similar to collect_value() the function may prematurely abort by returning a newly allocated string describing an error condition. To complete the string example: |[ gchar **string_p = collect_values[0].v_pointer; if (!string_p) return g_strdup_printf ("string location passed as NULL"); if (collect_flags & G_VALUE_NOCOPY_CONTENTS) *string_p = value->data[0].v_pointer; else *string_p = g_strdup (value->data[0].v_pointer); ]| And an illustrative version of lcopy_value() for reference-counted types: |[ GObject **object_p = collect_values[0].v_pointer; if (!object_p) return g_strdup_printf ("object location passed as NULL"); if (!value->data[0].v_pointer) *object_p = NULL; else if (collect_flags & G_VALUE_NOCOPY_CONTENTS) // always honour *object_p = value->data[0].v_pointer; else *object_p = g_object_ref (value->data[0].v_pointer); return NULL; ]|
+ * G_VALUE_HOLDS_INT64:
+ * @value: a valid #GValue structure

+ *
+ * A #GClosure represents a callback supplied by the programmer. It
+ * will generally comprise a function of some kind and a marshaller
+ * used to call it. It is the reponsibility of the marshaller to
+ * convert the arguments for the invocation from #GValue<!-- -->s into
+ * a suitable form, perform the callback on the converted arguments,
+ * and transform the return value back into a #GValue.
+ * In the case of C programs, a closure usually just holds a pointer
+ * to a function and maybe a data argument, and the marshaller
+ * converts between #GValue<!-- --> and native C types. The GObject
+ * library provides the #GCClosure type for this purpose. Bindings for
+ * other languages need marshallers which convert between #GValue<!--
+ * -->s and suitable representations in the runtime of the language in
+ * order to use functions written in that languages as callbacks.
+ * Within GObject, closures play an important role in the
+ * implementation of signals. When a signal is registered, the
+ * marshaller for any closure which is connected to this
+ * signal. GObject provides a number of C marshallers for this
+ * purpose, see the g_cclosure_marshal_*() functions. Additional C
+ * marshallers can be generated with the <link
+ * linkend="glib-genmarshal">glib-genmarshal</link> utility.  Closures
+ * can be explicitly connected to signals with
+ * g_signal_connect_closure(), but it usually more convenient to let
+ * GObject create a closure automatically by using one of the
+ * g_signal_connect_*() functions which take a callback function/user
+ * data pair.
+ * Using closures has a number of important advantages over a simple
+ * callback function/data pointer combination:

  * <listitem><para>

- * over from the parent class.

+ * which means that language bindings don't have to write individual glue
+ * for each callback type.
  * </para></listitem>
  * <listitem><para>
- * 3 - Invocation of the GBaseInitFunc() initializers of all parent
- * types and the class' type.

- * Since derived classes are partially initialized through a memory copy
- * of the parent class, the general rule is that GBaseInitFunc() and

- * GClassInitFunc() should only care about initializing static

- * or reference counted resources) are better handled by a GBaseInitFunc()

- * Returns: a newly created parameter specification

+ * and interfaces using g_type_module_register_type() and
+ * g_type_module_add_interface().  As long as any instances of these
+ * types and interface implementations are in use, the module is kept
+ * loaded. When the types and interfaces are gone, the module may be

+ * will be reloaded. Note that the last unref can not happen in module
+ * code, since that would lead to the caller's code being unloaded before
+ * g_object_unref() returns to it.
+ * Keeping track of whether the module should be loaded or not is done by
+ * using a use count - it starts at zero, and whenever it is greater than
+ * zero, the module is loaded. The use count is maintained internally by
+ * the type system, but also can be explicitly controlled by

+ * a module for the first type, g_type_module_use() will be used to load

- * The type system will perform a deep copy of this structure, so its memory
- * does not need to be persistent across invocation of
- * g_param_type_register_static().
+ * GObject is the fundamental type providing the common attributes and
+ * methods for all object types in GTK+, Pango and other libraries
+ * based on GObject.  The GObject class provides methods for object

+ * #GInitiallyUnowned is derived from #GObject. The only difference between
+ * the two is that the initial reference of a #GInitiallyUnowned is flagged
+ * as a <firstterm>floating</firstterm> reference.
+ * This means that it is not specifically claimed to be "owned" by
+ * any code portion. The main motivation for providing floating references is
+ * C convenience. In particular, it allows code to be written as:
+ * |[
+ * container = create_container();
+ * container_add_child (container, create_child());
+ * ]|
+ * If <function>container_add_child()</function> will g_object_ref_sink() the

+ * Without floating references, <function>container_add_child()</function>
+ * can only g_object_ref() the new child, so to implement this code without

+ * |[
+ * Child *child;
+ * container = create_container();
+ * child = create_child();
+ * container_add_child (container, child);
+ * g_object_unref (child);
+ * ]|
+ * The floating reference can be converted into
+ * an ordinary reference by calling g_object_ref_sink().
+ * For already sunken objects (objects that don't have a floating reference
+ * anymore), g_object_ref_sink() is equivalent to g_object_ref() and returns
+ * a new reference.
+ * Since floating references are useful almost exclusively for C convenience,
+ * language bindings that provide automated reference and memory ownership
+ * maintenance (such as smart pointers or garbage collection) therefore don't
+ * need to expose floating references in their API.
+ * </para>
+ * Some object implementations may need to save an objects floating state
+ * across certain code portions (an example is #GtkMenu), to achive this, the
+ * following sequence can be used:
+ * |[
+ * // save floating state
+ * gboolean was_floating = g_object_is_floating (object);
+ * g_object_ref_sink (object);
+ * // protected code portion
+ * ...;

+ * The user-provided signal handlers are called in the order they were

+ * All handlers may prematurely stop a signal emission, and any number of
+ * handlers may be connected, disconnected, blocked or unblocked during
+ * a signal emission.
+ * There are certain criteria for skipping user handlers in stages 2 and 4
+ * of a signal emission.
+ * First, user handlers may be <emphasis>blocked</emphasis>, blocked handlers are omitted
+ * during callback invocation, to return from the "blocked" state, a

+ * Second, upon emission of a %G_SIGNAL_DETAILED signal, an additional
+ * "detail" argument passed in to g_signal_emit() has to match the detail

+ * @n_structs: the number of elements to allocate
  *
- * A #GClosure represents a callback supplied by the programmer. It
- * will generally comprise a function of some kind and a marshaller
- * used to call it. It is the reponsibility of the marshaller to
- * convert the arguments for the invocation from #GValue<!-- -->s into
- * a suitable form, perform the callback on the converted arguments,
- * and transform the return value back into a #GValue.
- * In the case of C programs, a closure usually just holds a pointer
- * to a function and maybe a data argument, and the marshaller
- * converts between #GValue<!-- --> and native C types. The GObject
- * library provides the #GCClosure type for this purpose. Bindings for
- * other languages need marshallers which convert between #GValue<!--
- * -->s and suitable representations in the runtime of the language in
- * order to use functions written in that languages as callbacks.
- * Within GObject, closures play an important role in the
- * implementation of signals. When a signal is registered, the
- * marshaller for any closure which is connected to this
- * signal. GObject provides a number of C marshallers for this
- * purpose, see the g_cclosure_marshal_*() functions. Additional C
- * marshallers can be generated with the <link
- * linkend="glib-genmarshal">glib-genmarshal</link> utility.  Closures
- * can be explicitly connected to signals with
- * g_signal_connect_closure(), but it usually more convenient to let
- * GObject create a closure automatically by using one of the
- * g_signal_connect_*() functions which take a callback function/user
- * data pair.
- * Using closures has a number of important advantages over a simple
- * callback function/data pointer combination:
- * <itemizedlist>
- * <listitem><para>
- * Closures allow the callee to get the types of the callback parameters,
- * which means that language bindings don't have to write individual glue
- * for each callback type.
- * </para></listitem>
- * <listitem><para>
- * The reference counting of #GClosure makes it easy to handle reentrancy

- * and its parameters won't be freed until the invocation finishes.

 /**
- * GRegexCompileFlags:
- * @G_REGEX_CASELESS: Letters in the pattern match both upper- and lowercase letters. This option can be changed within a pattern by a "(?i)" option setting.
- * @G_REGEX_MULTILINE: By default, GRegex treats the strings as consisting of a single line of characters (even if it actually contains newlines). The "start of line" metacharacter ("^") matches only at the start of the string, while the "end of line" metacharacter ("$") matches only at the end of the string, or before a terminating newline (unless #G_REGEX_DOLLAR_ENDONLY is set). When #G_REGEX_MULTILINE is set, the "start of line" and "end of line" constructs match immediately following or immediately before any newline in the string, respectively, as well as at the very start and end. This can be changed within a pattern by a "(?m)" option setting.
- * @G_REGEX_DOTALL: A dot metacharater (".") in the pattern matches all characters, including newlines. Without it, newlines are excluded. This option can be changed within a pattern by a ("?s") option setting.
- * @G_REGEX_EXTENDED: Whitespace data characters in the pattern are totally ignored except when escaped or inside a character class. Whitespace does not include the VT character (code 11). In addition, characters between an unescaped "#" outside a character class and the next newline character, inclusive, are also ignored. This can be changed within a pattern by a "(?x)" option setting.
- * @G_REGEX_ANCHORED: The pattern is forced to be "anchored", that is, it is constrained to match only at the first matching point in the string that is being searched. This effect can also be achieved by appropriate constructs in the pattern itself such as the "^" metacharater.
- * @G_REGEX_DOLLAR_ENDONLY: A dollar metacharacter ("$") in the pattern matches only at the end of the string. Without this option, a dollar also matches immediately before the final character if it is a newline (but not before any other newlines). This option is ignored if #G_REGEX_MULTILINE is set.
- * @G_REGEX_UNGREEDY: Inverts the "greediness" of the quantifiers so that they are not greedy by default, but become greedy if followed by "?". It can also be set by a "(?U)" option setting within the pattern.
- * @G_REGEX_RAW: Usually strings must be valid UTF-8 strings, using this flag they are considered as a raw sequence of bytes.
- * @G_REGEX_NO_AUTO_CAPTURE: Disables the use of numbered capturing parentheses in the pattern. Any opening parenthesis that is not followed by "?" behaves as if it were followed by "?:" but named parentheses can still be used for capturing (and they acquire numbers in the usual way).
- * @G_REGEX_OPTIMIZE: Optimize the regular expression. If the pattern will be used many times, then it may be worth the effort to optimize it to improve the speed of matches.
- * @G_REGEX_DUPNAMES: Names used to identify capturing subpatterns need not be unique. This can be helpful for certain types of pattern when it is known that only one instance of the named subpattern can ever be matched.
- * @G_REGEX_NEWLINE_CR: Usually any newline character is recognized, if this option is set, the only recognized newline character is '\r'.
- * @G_REGEX_NEWLINE_LF: Usually any newline character is recognized, if this option is set, the only recognized newline character is '\n'.
