void g_signal_emitv ( const GValue* instance_and_params, guint signal_id, GQuark detail, GValue* return_value )
Emits a signal. Signal emission is done synchronously. The method will only return control after all handlers are called or signal emission was stopped.
g_signal_emitv() doesn’t change
return_value if no handlers are
connected, in contrast to
g_signal_emit() and g_signal_emit_valist().
