Precision depends on the architecture; on modern systems you easily get 10ms or lower, but on older Windows machines (from the Win98 era) it was closer to 60ms. MS-DOS), it may give something more like wall clock time. Are there other approaches that can provide higher precision than getrusage()? I coded it up in Python and in C. see this here

In that sense, clock() is like an employee time clock (or the game clock in basketball, football, or whatever): it runs only some of the time, is likely to only run But if you use visual C compiler, then you will get error. –user2550754 Jan 9 '14 at 11:37 5 Yes, it'll work on windows with a c library that supports Browse other questions tagged c code-timing or ask your own question. http://stackoverflow.com/questions/2125219/how-to-get-the-running-of-time-of-my-program-with-gettimeofday So it will work on it.
So if you find that your code is running too slow, then it's clear that your algorithm (and probably your data structure also) is inadequate.E.g. Clocks_per_sec In C Especially as there's no clear winner for all cases. the quick-sort algorithm might be fastest in a general sense, but could be outperformed if certain qualities apply to the problem at hand - in which case you might even find Find answers to interview questions on C programming.

e.g. If the processor time used is not available or its value cannot be represented, the function returns the value (clock_t)-1. clock() is supposed the CPU time, not the wallclock time, so it should not matter (too much) if the machine is under load or not.
