which seems to require threading. If I compile without, it will hang indefinitely, I presume deadlocked. Is there a way this can be done without threading?
With much sweat, you could write your own timed polling loop and avoid threads, using hPutBufNonBlocking and hGetBufNonBlocking. I don't recommend it, except for fun or self-torture.
