DELAY(10.2)
NAME
delay, microdelay, addclock0link − small delays, clock interrupts
SYNOPSIS
voiddelay(int n);
voidmicrodelay(int n);
voidaddclock0link(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(10.2)) provides a better alternative to the busy waiting of these routines.
Addclock0link adds clockf to a list of functions to be executed at each clock interrupt.
