Sets our main struct and passes it to the parent class.
Finishes an operation started with g_dbus_connection_new().
Synchronously connects and sets up a D-Bus client connection for exchanging D-Bus messages with an endpoint specified by @address which must be in the D-Bus address format.
Synchronously sets up a D-Bus connection for exchanging D-Bus messages with the end represented by @stream.
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.
Emitted when the connection is closed.
Asynchronously invokes the @method_name method on the @interface_name D-Bus interface on the remote object at @object_path owned by @bus_name.
Finishes an operation started with g_dbus_connection_call().
Synchronously invokes the @method_name method on the @interface_name D-Bus interface on the remote object at @object_path owned by @bus_name.
Like g_dbus_connection_call() but also takes a #GUnixFDList object.
Finishes an operation started with g_dbus_connection_call_with_unix_fd_list().
Like g_dbus_connection_call_sync() but also takes and returns #GUnixFDList objects.
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).
Finishes an operation started with g_dbus_connection_close().
Synchronously closees @connection. The calling thread is blocked until this is done. See g_dbus_connection_close() for the asynchronous version of this method and more details about what it does.
Emits a signal.
Exports @action_group on @connection at @object_path.
Exports @menu on @connection at @object_path.
Asynchronously flushes @connection, that is, writes all queued outgoing message to the transport and then flushes the transport (using g_output_stream_flush_async()). This is useful in programs that wants to emit a D-Bus signal and then exit immediately. Without flushing the connection, there is no guaranteed that the message has been sent to the networking buffers in the OS kernel.
Finishes an operation started with g_dbus_connection_flush().
Synchronously flushes @connection. The calling thread is blocked until this is done. See g_dbus_connection_flush() for the asynchronous version of this method and more details about what it does.

Gets whether the process is terminated when @connection is closed by the remote peer. See #GDBusConnection:exit-on-close for more details.
The GUID of the peer performing the role of server when authenticating. See #GDBusConnection:guid for more details.
Retrieves the last serial number assigned to a #GDBusMessage on the current thread. This includes messages sent via both low-level API such as g_dbus_connection_send_message() as well as high-level API such as g_dbus_connection_emit_signal(), g_dbus_connection_call() or g_dbus_proxy_call().
Gets the credentials of the authenticated peer. This will always return %NULL unless @connection acted as a server (e.g. %G_DBUS_CONNECTION_FLAGS_AUTHENTICATION_SERVER was passed) when set up and the client passed credentials as part of the authentication process.
Gets the underlying stream used for IO.

Gets a D Object from the objects table of associations.
The notify signal is emitted on an object when one of its properties has been changed. Note that getting this signal doesn't guarantee that the value of the property has actually changed, it may also be emitted when the setter for the property is called to reinstate the previous value.
Find the #GParamSpec with the given name for an interface. Generally, the interface vtable passed in as @g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().
Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created #GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property.
Lists the properties of an interface.Generally, the interface vtable passed in as @g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().
Increases the reference count of the object by one and sets a callback to be called when all other references to the object are dropped, or when this is already the last reference to the object and another reference is established.
Adds a weak reference from weak_pointer to @object to indicate that the pointer located at @weak_pointer_location is only valid during the lifetime of @object. When the @object is finalized, @weak_pointer will be set to %NULL.
Creates a binding between @source_property on @source and @target_property on @target. Whenever the @source_property is changed the @target_property is updated using the same value. For instance:
Complete version of g_object_bind_property().
Creates a binding between @source_property on @source and @target_property on @target, allowing you to set the transformation functions to be used by the binding.
This is a variant of g_object_get_data() which returns a 'duplicate' of the value. @dup_func defines the meaning of 'duplicate' in this context, it could e.g. take a reference on a ref-counted object.
This is a variant of g_object_get_qdata() which returns a 'duplicate' of the value. @dup_func defines the meaning of 'duplicate' in this context, it could e.g. take a reference on a ref-counted object.
This function is intended for #GObject implementations to re-enforce a floating[floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling g_object_ref_sink().
Increases the freeze count on @object. If the freeze count is non-zero, the emission of "notify" signals on @object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.
Gets a named field from the objects table of associations (see g_object_set_data()).
Gets a property of an object. @value must have been initialized to the expected type of the property (or a type to which the expected type can be transformed) using g_value_init().
This function gets back user data pointers stored via g_object_set_qdata().
Gets properties of an object.
Gets @n_properties properties for an @object. Obtained properties will be set to @values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.
Checks whether @object has a floating[floating-ref] reference.
Emits a "notify" signal for the property @property_name on @object.
Emits a "notify" signal for the property specified by @pspec on @object.
Increases the reference count of @object.
Increase the reference count of @object, and possibly remove the floating[floating-ref] reference, if @object has a floating reference.
Removes a reference added with g_object_add_toggle_ref(). The reference count of the object is decreased by one.
Removes a weak reference from @object that was previously added using g_object_add_weak_pointer(). The @weak_pointer_location has to match the one used with g_object_add_weak_pointer().
Compares the user data for the key @key on @object with @oldval, and if they are the same, replaces @oldval with @newval.
Compares the user data for the key @quark on @object with @oldval, and if they are the same, replaces @oldval with @newval.
Releases all references to other objects. This can be used to break reference cycles.
Each object carries around a table of associations from strings to pointers. This function lets you set an association.
Like g_object_set_data() except it adds notification for when the association is destroyed, either by setting it to a different value or when the object is destroyed.
Sets a property on an object.
This sets an opaque, named pointer on an object. The name is specified through a #GQuark (retrived e.g. via g_quark_from_static_string()), and the pointer can be gotten back from the @object with g_object_get_qdata() until the @object is finalized. Setting a previously set user data pointer, overrides (frees) the old pointer set, using #NULL as pointer essentially removes the data stored.
This function works like g_object_set_qdata(), but in addition, a void (*destroy) (gpointer) function may be specified which is called with @data as argument when the @object is finalized, or the data is being overwritten by a call to g_object_set_qdata() with the same @quark.
Sets properties on an object.
Sets @n_properties properties for an @object. Properties to be set will be taken from @values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.
Remove a specified datum from the object's data associations, without invoking the association's destroy handler.
This function gets back user data pointers stored via g_object_set_qdata() and removes the @data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example: |[<!-- language="C" --> void object_add_to_user_list (GObject *object, const gchar *new_string) { // the quark, naming the object data GQuark quark_string_list = g_quark_from_static_string ("my-string-list"); // retrive the old string list GList *list = g_object_steal_qdata (object, quark_string_list);
Reverts the effect of a previous call to g_object_freeze_notify(). The freeze count is decreased on @object and when it reaches zero, queued "notify" signals are emitted.
Decreases the reference count of @object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).
This function essentially limits the life time of the @closure to the life time of the object. That is, when the object is finalized, the @closure is invalidated by calling g_closure_invalidate() on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, g_object_ref() and g_object_unref() are added as marshal guards to the @closure, to ensure that an extra reference count is held on @object during invocation of the @closure. Usually, this function will be called on closures that use this @object as closure data.
Adds a weak reference callback to an object. Weak references are used for notification when an object is finalized. They are called "weak references" because they allow you to safely hold a pointer to an object without calling g_object_ref() (g_object_ref() adds a strong reference, that is, forces the object to stay alive).
Removes a weak reference callback to an object.
Clears a reference to a #GObject.

Helper function for constructing #GAsyncInitable object. This is similar to g_object_new_valist() but also initializes the object asynchronously.
Helper function for constructing #GAsyncInitable object. This is similar to g_object_newv() but also initializes the object asynchronously.
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.
Finishes asynchronous initialization and returns the result. See g_async_initable_init_async().
Finishes the async construction for the various g_async_initable_new calls, returning the created object or %NULL on error.

The #GDBusConnection type is used for D-Bus connections to remote peers such as a message buses. It is a low-level API that offers a lot of flexibility. For instance, it lets you establish a connection over any transport that can by represented as an #GIOStream.
This class is rarely used directly in D-Bus clients. If you are writing a D-Bus client, it is often easier to use the g_bus_own_name(), g_bus_watch_name() or g_dbus_proxy_new_for_bus() APIs.
As an exception to the usual GLib rule that a particular object must not be used by two threads at the same time, #GDBusConnection's methods may be called from any thread. This is so that g_bus_get() and g_bus_get_sync() can safely return the same #GDBusConnection when called from any thread.
Most of the ways to obtain a #GDBusConnection automatically initialize it (i.e. connect to D-Bus): for instance, g_dbus_connection_new() and g_bus_get(), and the synchronous versions of those methods, give you an initialized connection. Language bindings for GIO should use g_initable_new() or g_async_initable_new_async(), which also initialize the connection.
If you construct an uninitialized #GDBusConnection, such as via g_object_new(), you must initialize it via g_initable_init() or g_async_initable_init_async() before using its methods or properties. Calling methods or accessing properties on a #GDBusConnection that has not completed initialization successfully is considered to be invalid, and leads to undefined behaviour. In particular, if initialization fails with a #GError, the only valid thing you can do with that #GDBusConnection is to free it with g_object_unref().
