Linux had them per-thread until recently, but in current versions (including FC4) it is per-process. If you want more options for timers, you can use timer_create and the related interfaces. -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/fedora-devel-list
