    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.
