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.


CONFORMS 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  pro-
       gram and the end to get maximum portability.

       The times() function call returns more information.
