NAME
        TimeDelay -- Return after a period of time has elapsed.

   SYNOPSIS
        Error = TimeDelay( unit, seconds, microseconds )
        D0                 D0    D1       D2

        long timedelay( long, ulong, ulong );

   FUNCTION
        Waits for the period of time specified before returning to the
        the caller.

   INPUTS
        unit -- timer.device unit to open for this command.
        Seconds -- The seconds field of a timerequest is filled with
            this value. Check the documentation for what a particular
            timer.device unit expects there.
        MicroSeconds -- The microseconds field of a timerequest is
            filled with this value. Check the documentation for what
            a particular timer.device units expects there.

   RESULTS
        Error -- will be zero if all went well; otherwise, non-zero.

   NOTES
        Two likely reasons for failures are invalid unit numbers or
        no more free signal bits for this task.

        While this function first appears in V37 amiga.lib, it works
        on Kickstart V33 and higher.
