g_signal_emit_valist (
  GObjectTypeInstance* instance,
  guint signal_id,
  GQuark detail,
  va_list var_args


Emits a signal. Signal emission is done synchronously. The method will only return control after all handlers are called or signal emission was stopped.

Note that g_signal_emit_valist() resets the return value to the default if no handlers are connected, in contrast to g_signal_emitv().
