alias Gio::DBusInterfaceMethodCallFunc
Overview
The type of the method_call function in #GDBusInterfaceVTable.
interface_name may be NULL if not specified by the sender, although it’s
encouraged for the sender to set it. If unset, and the object has only one
method (across all interfaces) matching method_name, that method is invoked.
Otherwise, behaviour is implementation defined. See the
D-Bus specification.
It is recommended to return Gio::DBusError#UNKNOWN_METHOD.
