Hi guys, Just wondering if there''s something similar to QueryPerformanceCounter/QueryPerformanceFrequency generally supported by the Linux platform? I''ve looked into the RDTSC instruction, but would like to steer away from x86 specific stuff if possible. Regards, Tom L

Other functions you might be interested in are clock_gettime (potential nanosecond accuracy; standard POSIX, but relatively new) and ftime (millisecond accuracy; standard POSIX).

The gettimeofday function that Fruny mentioned is standard for BSD (but supported in Linux and many BSD derived unixes), if you''re interested.
