Okay, here is what I want to do: I have a C Program that I have the source for and want to hook with python into that. What I want to do is: run the C program as a subprocess. The C programm gets its "commands" from its stdin and sends its state to stdout. Thus I have some kind of dialog over stdin.
So, once I start the C Program from the shell, I immediately get its output in my terminal. If I start it from a subprocess in python and use python's sys.stdin/sys.stdout as the subprocess' stdout/stdin I also get it immediately. BUT If I use PIPE for both (so I can .write() on the stdin and .read() from the subprocess' stdout stream (better: file descriptor)) reading from the subprocess stdout blocks forever. If I write something onto the subprocess' stdin that causes it to somehow proceed, I can read from its stdout. Thus a useful dialogue is not possible.
