I can't speak to the blocking semantics, but if you plan to have more than one process reading at once, FIFOs won't do what you want. I suspect unix sockets are closer to the behavior you're after. IIRC using them in datagram mode may give you the ability to write whether or not anyone is listening. Otherwise you'll have to do the normal listen, accept, select/poll loop. Craig
