Any alarm function that has precision of microsecond?
I have to use alarm function, and it seems I cannot use
usleep or nanosleep, cause the document says not
to mixing them.
It didn't say don't mix up alarm and pause, but I wonder
if alarm and pause are mixed, some problem will arise? | j***y

you can try setitimer for BSD based (4.2 or later) system,
or settimer for POSIX based system. They have higher resolution
than alarm, although the accuracy may be machine-dependent.
