Well, it depends what event and under what circumstances.

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
