    Hi all. I am trying to set up a C++ program which will continuously
    read stdin from another applications stdout. I will continue reading
    until I read a message that will indicate to stop. Does anyone have
    any ideas on how I can do this?

    Thanks for responses.

  2. AFAIK, only the OS can control where stdin comes from.

    In MS-DOS or Unix (don't know about other platforms), use a pipe

    qwert | yuiop

    will run qwert, the stdout of which becomes the stdin of yuiop.
