     DELAY(9)                                                 DELAY(9)

     NAME
          delay, microdelay, addclock0link - small delays, clock
          interrupts

     SYNOPSIS
          void delay(int n)

          void microdelay(int n)

          void addclock0link(void(*clockf)(void))

     DESCRIPTION
          Delay busy waits for n milliseconds, forced to be at least
          one millisecond.

          Microdelay is similar, but busy waits for n microseconds.

          For delays on the order of clock ticks, tsleep (see
          sleep(9)) provides a better alternative to the busy waiting
          of these routines.

          Addclock0link adds clockf to a list of functions to be exe-
          cuted at each clock interrupt on the first processor.
