clock time in milliseconds into a c program

[Claudiu Dragalina-Paraipan]

Or you can use PERFMON. Check manual page for perfmon.
It gives you access to internal counters of CPU.

Of course this is a subjective measurement, since, AFAIK, the counters
are not kept separately for every process, but for entire system,
including kernel.
Maybe repeating the same measurement for many times, with a system
running no other CPU consumers, you will get a more accurate
measurement
