In my program, I want to give the OS a chance to process events at one
point,
but I don't want to sleep if there are no pending events.
So I do:
if (EvtEventAvail() || EvtSysEventAvail(false))
{
EvtGetEvent(&event, 1); // can't give 0
// Process event as normal...
// (And yes, I handle the appStopEvent if needed. :)
}
Now, in theory, the tick wait in EvtGetEvent should be irrelevant if the
queue already has an event to process. But when I set that number high,
the program lost control. With it set at 1, I'm finding I'm getting
nilEvents!
My understanding is that you don't get nilEvents unless your EvtGetEvent
timed out
while waiting for an event.
But if EvtSysEventAvail(false) works, there should always be an event to
get!
I can't afford to lose a tick of time waiting for a nil Event - any
ideas why my
screening doesn't catch that there are no events?
Thanks!
