Re: problem with usleep?



Read the man page for usleep very carefully. usleep can be interrupted at
any time by another signal.

If your trying to get a real time affect from usleep, it'll never happen. In
other words, usleep is not garanteed to delay for the total amount of time
that you pass to it.

Personally I only use usleep when I want to give other threads or processes
a chance for some cpu cycles and usleep(1) does the trick.

Try using nanosleep instead ( again, read the man page carefully ).
nanosleep will allow you to determine how long you slept.
