|
|
* @short_description: Client-side D-Bus interface proxy
|
|
* @include: gio/gio.h
|
|
*
|
|
* #GDBusProxy is a base class used for proxies to access a D-Bus
|
|
* interface on a remote object. A #GDBusProxy can be constructed for
|
|
* both well-known and unique names.
|
|
*
|
|
* By default, #GDBusProxy will cache all properties (and listen to
|
|
* changes) of the remote object, and proxy all signals that get
|
|
* emitted. This behaviour can be changed by passing suitable
|
|
* #GDBusProxyFlags when the proxy is created. If the proxy is for a
|
|
* well-known name, the property cache is flushed when the name owner
|
|
* vanishes and reloaded when a name owner appears.
|
|
*
|
|
* If a #GDBusProxy is used for a well-known name, the owner of the
|
|
* name is tracked and can be read from
|
|
* #GDBusProxy:g-name-owner. Connect to the #GObject::notify signal to
|
|
* get notified of changes. Additionally, only signals and property
|
|
* changes emitted from the current name owner are considered and
|
|
* calls are always sent to the current name owner. This avoids a
|
|
* number of race conditions when the name is lost by one owner and
|
|
* claimed by another. However, if no name owner currently exists,
|
|
* then calls will be sent to the well-known name which may result in
|
|
* the message bus launching an owner (unless
|
|
* %G_DBUS_PROXY_FLAGS_DO_NOT_AUTO_START is set).
|
|
*
|
|
* The generic #GDBusProxy::g-properties-changed and
|
|
* #GDBusProxy::g-signal signals are not very convenient to work with.
|
|
* Therefore, the recommended way of working with proxies is to subclass
|
|
* #GDBusProxy, and have more natural properties and signals in your derived
|
|
* class. This [example][gdbus-example-gdbus-codegen] shows how this can
|
|
* easily be done using the [gdbus-codegen][gdbus-codegen] tool.
|
|
*
|
|
* A #GDBusProxy instance can be used from multiple threads but note
|
|
* that all signals (e.g. #GDBusProxy::g-signal, #GDBusProxy::g-properties-changed
|
|
* and #GObject::notify) are emitted in the
|
|
* [thread-default main context][g-main-context-push-thread-default]
|
|
* of the thread where the instance was constructed.
|
|
*
|
|
* An example using a proxy for a well-known name can be found in
|
|
* [gdbus-example-watch-proxy.c](https://git.gnome.org/browse/glib/tree/gio/tests/gdbus-example-watch-proxy.c)

|
* @flags: Flags from the #GDBusCallFlags enumeration.
|
|
* @timeout_msec: The timeout in milliseconds (with %G_MAXINT meaning
|
|
* "infinite") or -1 to use the proxy default timeout.
|
|
* @fd_list: (nullable): A #GUnixFDList or %NULL.
|
|
* @out_fd_list: (out) (optional): Return location for a #GUnixFDList or %NULL.
|
|
* @cancellable: (nullable): A #GCancellable or %NULL.
|
|
* @error: Return location for error or %NULL.
|
|
*
|
|
* Like g_dbus_proxy_call_sync() but also takes and returns #GUnixFDList objects.
|
|
*
|
|
* This method is only available on UNIX.
|
|
*
|
|
* Returns: %NULL if @error is set. Otherwise a #GVariant tuple with
|
|
* return values. Free with g_variant_unref().
|

* Since: 2.30
