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?

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.
