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 executed
at each clock interrupt on the first processor. |
