I'm sure that what you need here is not EOF's down pipes but a *protocol*. After all, EOF means that the other end of the pipe has been closed, and not some other magical event. > Is it actually hard to implement in any version of UNIX? I'm also sure that it wouldn't be very hard to break pipes too. At least it'd be a step forward in the apparent quest to break everything, that up till now worked in the stated way. > Wouldn't be very compatible with the rest of the world ... Exactly, it wouldn't be very compatible. But I see that it's already been done at RAND with that ridiculous eofp() junk. I just dread the thought of "eofp() meets _filbuf()".
