May 13, 2009 Hey, Ted
Thanks for the information about the sleep API. On a recent project, we had a requirement to ensure that two operations were at least a microsecond apart, but a full second proved to be far too long. (Seconds add up quickly!) We created a DLYJOBSML (Delay Job for Small Duration) command and invoked the usleep API in the CPP.
Like sleep, usleep also delays a job. The difference is that the usleep parameter denotes milliseconds, rather than whole seconds. You might say that sleep is like going to bed at night, whereas usleep only takes a nap.
