If you read for input with zero timeout, and then only try and process the data if there's anything to be processed, then the loop will run through both options, regardless of whether there's data on both inputs or not. Don't forget to add in something to stop it looping at high speed, though, or it'll eat all your CPU while it's not doing anything.

An alternative solution is to fork off a process for each tcp connection you're making, as you don't appear to be doing any cross communication between the two in your example code. That way you can wait indefinately on input still.

    If I read for input with zero timeout, the program immediately quits, saying: read timed-out at line 29

    I can't use a different process, because I intend to include cross communication in the future.
