* Schedule a callback.
* \param ival interval before the callback should be made in ms
* \param callback callback function
* \param p user parameter, passed to callback function
* The callback function will be called as soon as possible after t ms have
nserror win32_schedule(int ival, void (*callback)(void *p), void *p);
* Process scheduled callbacks up to current time.
* This walks the list of outstanding scheduled events and dispatches
* them if they have met their scheduled time. Due to legacy issues
* there are a couple of subtleties with how this operates:
* - Generally there are so few entries on the list the overhead of
* ordering the list exceeds the cost of simply enumerating them.
* - The scheduled time is the time *after* which we should call the
* operation back, this can result in the next scheduled time
* being zero. This is exceedingly rare as the core schedules in
* 10ms (cs) quanta and we almost always get called to schedule
* after the event time.
* - The callbacks can cause the schedule list to be re-arranged added
* to or even completely deleted. This means we must reset the
* list enumeration to the beginning every time an event is
* @return The number of milliseconds untill the next scheduled event
* or -1 for no event.
* LOG all current scheduled events.
