[net.unix-wizards] Looking for fast timer

Hello there!

We are looking for some type of timer function, such as alarm(2),
which will give us a granularity of 1/60th of a second. If I can recall
correctly, I once read something about /dev/ft. Does anybody know
about this?? Thanks.

Cheers!

If you are running 4.2BSD, you can use setitimer(2).  The resolution
provided is that of the system clock.  See the code for sleep() in the
C library for a usage example, or I can mail you a copy of our xsleep()
routine whose argument is a double (hint).
