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
Otherwise, if true is returned, signal emission continues. If no handlers return
false, then the method is dispatched. If
interface has an enclosing
DBusObjectSkeleton, then the
authorize_method signal handlers run before the handlers for
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 DBusObjectSkeleton, if any) and
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.
true if the call is authorized, false otherwise.
