g_authorize_method (

  GDBusMethodInvocation* invocation,
  gpointer user_data


Emitted when a method is invoked by a remote caller and used to determine if the method call is authorized.

Note that this signal is emitted in a thread dedicated to handling the method call so handlers are allowed to perform blocking IO. This means that it is appropriate to call e.g. polkit_authority_check_authorization_sync() with the POLKIT_CHECK_AUTHORIZATION_FLAGS_ALLOW_USER_INTERACTION flag set.

If FALSE is returned then no further handlers are run and the signal handler must take a reference to invocation and finish handling the call (e.g. return an error via g_dbus_method_invocation_return_error()).

Otherwise, if TRUE is returned, signal emission continues. If no handlers return FALSE, then the method is dispatched. If interface has an enclosing GDBusObjectSkeleton, then the GDBusObjectSkeleton::authorize-method signal handlers run before the handlers for this signal.

The default class handler just returns TRUE.

Please note that the common case is optimized: if no signals handlers are connected and the default class handler isn’t overridden (for both interface and the enclosing GDBusObjectSkeleton, if any) and GDBusInterfaceSkeleton:g-flags does not have the G_DBUS_INTERFACE_SKELETON_FLAGS_HANDLE_METHOD_INVOCATIONS_IN_THREAD flags set, no dedicated thread is ever used and the call will be handled in the same thread as the object that interface belongs to was exported in.

Default handler:

The default handler is called after the handlers added via g_signal_connect().

invocation GDBusMethodInvocation

A GDBusMethodInvocation.

 The data is owned by the caller of the function.

Return value

Returns: gboolean

TRUE if the call is authorized, FALSE otherwise.
