If the delegate parameter isn't "owned" (i.e. doesn't have a GDestroyNotify parameter in the C code), there is no way for valac to know when to free the data, so it frees it as soon as it goes out of scope. Actually, many of the functions having this problem have a common property : they are called only once (This is the (scope async) annotation of gobject-introspection), so I guess something like this could be done in valac. Maybe this is worth a bug report? HTH, Abderrahim _______________________________________________ vala-list mailing list vala-list@gnome.org http://mail.gnome.org/mailman/listinfo/vala-list
