Like select(2) or poll(2) would do?
You seem to what something low-level.
Well, my point is that I don't really want to deal with the file descriptors. What I'd really like to do is to register a call-back function; similar to the way signal handlers work. I don't want to wait for something to happen -- I'd like to be notified when something happens. By the way, the source code for the module says: -- Note: threadDelay, threadWaitRead and threadWaitWrite -- aren't really functional on Win32, but left in there -- because lib code (still) uses them (the manner in which -- they're used doesn't cause problems on a Win32 platform -- though.) So I guess I can't really use them in code that's supposed to be portable among different platforms? Maybe 'forkOS' combined with calling poll() through FFI really is the best solution? I seem to recall reading somewhere that the threaded RTS was more efficient for these applications anyway? Peter
