clock

CLOCK(3)						     Linux Programmer's Manual							  CLOCK(3)

NAME

       clock - Determine processor time

SYNOPSIS

       #include <time.h>

       clock_t clock(void);

DESCRIPTION

       The clock() function returns an approximation of processor time used by the program.

RETURN VALUE

       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.  If the processor
       time used is not available or its value cannot be represented, the function returns the value (clock_t)-1.

CONFORMING TO

       ANSI C.	POSIX requires that CLOCKS_PER_SEC equals 1000000 independent of the actual resolution.

NOTES

       The C standard allows for arbitrary values at the start of the program; subtract the value returned from a call to clock() at the start	of
       the program to get maximum portability.

       Note that the time can wrap around.  On a 32bit system where CLOCKS_PER_SEC equals 1000000 this function will return the same value approx-
       imately every 72 minutes.

       On several other implementations, the value returned by clock() also includes the times of any children whose status has been collected via
       wait() (or another wait-type call).  Linux does not include the times of waited-for children in the value returned by clock().  The times()
       function, which explicitly returns (separate) information about the caller and its children, may be preferable.
