Table of Contentsclock - Determine processor time #include <time.h>
clock_t clock(void); The clock() function returns an approximation of processor time used by the program. The value returned is the CPU time used so far as a clock_t; to get the number of seconds used, divide by CLOCKS_PER_SEC. ANSI C The C standard allows for arbitrary values at the start of the program; take the difference between the value returned from a call to clock() at the start of the program and the end to get maximum portability. The times() function call returns more information.
