I am using C language and Linux as my programming platform in embedded device.
My question is, how to correctly retrieve the current processor time(tick). I am using clock() function in time.h and it seems I am getting inconsistent value.
Thanks.
The
clock()function measures the CPU time consumed by your process. It doesn’t increment while your process is sleeping or blocked.If you want a high resolution clock that advances continually, use
clock_gettime(CLOCK_MONOTONIC, ..).
