|
* Instances of the #GDBusMethodInvocation class are used when
|
|
* handling D-Bus method calls. It provides a way to asynchronously
|
|
* return results and errors.
|
|
*
|
|
* The normal way to obtain a #GDBusMethodInvocation object is to receive
|
|
* it as an argument to the handle_method_call() function in a
|
|
* #GDBusInterfaceVTable that was passed to g_dbus_connection_register_object().
