<h3>CLOCK(3)            Linux Programmer's Manual            CLOCK(3)
</h3>
<h3>NAME
</h3>       clock - Determine processor time
<h3>SYNOPSIS
</h3>       #include <time.h>
       clock_t clock(void);
<h3>DESCRIPTION
</h3>       The clock() function returns an approximation of processor
       time used by the program.
<h3>RETURN VALUE
</h3>       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.
<h3>CONFORMS TO
</h3>       ANSI C
<h3>BUGS
</h3>       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.
