In > case of g_object_get_property() that terminator is 'NULL'. Actually, g_object_get_property() is not a vararg function, but g_object_get() - the function you're supposed to use here - is. Assuming the property "port" is of type G_TYPE_INT, it's either   gint port;   g_object_get (obj, "port", &port, NULL); or something like:   GValue val = { 0, };   gint port;   g_value_init (&val, G_TYPE_INT);   g_object_get_property (G_OBJECT (obj), "port", &val);   port = g_value_get_int (&val);   g_value_unset (&val); Cheers   -Tim </blockquote></div>
