DBUS_METHOD_INVOCATION_HANDLED

The value returned by handlers of the signals generated by the gdbus-codegen tool to indicate that a method call has been handled by an implementation. It is equal to true, but using this macro is sometimes more readable.

g_dbus_method_invocation_return_error (invocation, ...);
return TRUE;    // handled
