10 void microdelay(int µs)
13 Timer* addclock0link(void(*clockf)(void), int ms)
18 milliseconds, forced to be at least one millisecond on some architectures.
21 works exactly the same as
23 but using microseconds instead.
25 For delays on the order of clock ticks,
29 provides a better alternative to the busy waiting of these routines.
32 adds a new periodic timer to the current processor's timer list, with
38 is zero a default clock is used, it will panic otherwise (i.e.
