Is there an equivalent C function in linux for reading the CPU counter and its frequency? I am looking for something similair to QueryPerformanceCounter function that reads the 64bit counter in modern CPU's

<code>clock_gettime(2)</code>, with an argument of <code>CLOCK_REALTIME_HR</code>.

clock_gettime() with CLOCK_MONOTONIC_RAW

C linux equivalent of windows QueryPerformanceCounter

clock_gettime(2), with an argument of CLOCK_REALTIME_HR.
