Write to stdin and read from stdout

[bjohnson]

Hello,

I was wondering how I could write something to stdin and read from stdout or stderr. I understand that stdin is normally for incoming data (from the keyboard) and that we usually write to stdout and/or stderr. I believe I might need to work with the file descriptors and use pipes but I'm really not sure how that works. If anyone is able to help it would be greatly appreciated.

Thanks,
Bill
