        SYNTAX

        long clock ( )


        DESCRIPTION

        Clock returns the amount of CPU time (in microseconds) used since
        the first call to clock.  The time reported is the sum of the
        user and system times of the calling process and its terminated
        child processes for which it has executed wait(2) or system(3S).

        The resolution of the clock is 10 milliseconds on Data General
        processors.


        SEE ALSO

        times(2), wait(2), system(3S).


        BUGS

        The value returned by clock is defined in microseconds for
        compatibility with systems that have CPU clocks with much higher
        resolution.  Because of this, the value returned will wrap around
        after accumulating only 2147 seconds of CPU time (about 36
        minutes).
