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.
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.
