It will be much faster, but you can't use them in many cases. The big problem is if you have sevaral variables which have to change together, for example if you have an (x, y) coordinate pair. If you don't use a mutex, a writer thread could be only half way though updating the coordinate when a reader thread tests the values. _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
