Clock_gettime() measures ELAPSED time, or the time difference
of an external clock.  I don't want to measure ELAPSED time
because it may include other things on a multi-tasking system.

I want only the exact CPU time of my process and that is measured
with clock().

But I am not sure how multi-threading with clock() will behave
since I am only starting to investigate multi-threading.
