Note that high resolution timers under Unix are ___NOT___ guaranteed
to be accurate, and I can state with utter confidence that under
HP-UX, Solaris, Irix and AIX they are in fact very inaccurate at the
nanosecond level (thing about the ratio of nanoseconds to clock speeds
for one).
That said, the API set you are interested in are under the getitimer()
man pages, are derived from BSD, and have yet to be defined by ANSI.
They are extremely common under Unix however (haven't found a *nix
platform without them).
