The are single-threading and multi-threading programs. An event can be triggered by a counter, timer, signal, inotify, mutex lock/ unlock, barrier, polling, etc. Some of these logical constructs are generic, others are composites of existing ones. Often you put these logical constructs in a loop, perhaps with your own added timing or break-out logic. $ apropos timer $ apropos signal $ apropos pthread $ propos notify $ apropos event $ apropos sleep $ apropos poll JB -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
