Hey folks,
I have a worker thread that is only slowly polling. I would like to be
able wake him up from a different thread though. A bit like the
select(2) pattern. So what I do is:
...
pollingCondition = [[NSCondition alloc] init];
...
- (void) pollNow
{
[pollingCondition lock];
[pollingCondition signal];
[pollingCondition unlock];
}
- (void) workerThread:(id)arg
...
while (!quit) {
[pollingCondition lock];
[pollingCondition waitUntilDate: [NSDate
dateWithTimeIntervalSinceNow:SLEEP]];
[pollingCondition unlock];
...
}
...
}
Is it OK to do it like that? Is there a better way?
I've seen an "unlocked when not locked" and don't understand how this
could happen.
cheers
