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.

CONFORMING TO

     ANSI C

BUGS

     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.
