clock---cumulative processor time

Synopsis 
#include <time.h>
clock_t clock(void);
Description
Calculates the best available approximation of the cumulative amount of time used by your program since it started. To convert the result into seconds, divide by the macro CLOCKS_PER_SEC.


Returns
The amount of processor time used so far by your program, in units defined by the machine-dependent macro CLOCKS_PER_SEC. If no measurement is available, the result is -1.


Portability
ANSI C requires clock and CLOCKS_PER_SEC.

Supporting OS subroutine required: times.
