Even the g_once magic is not enough because they would have separate data sections for the static cached type id. So the get_type() for the failed registration would have G_TYPE_INVALID. But even if you were careful to do a g_type_from_name() as a fallback, you still risk the statically linked implementations being incompatible from version skew. _______________________________________________ desktop-devel-list mailing list desktop-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/desktop-devel-list
