If you are asking what I think you're asking, you need
to read up on the "subprocess" module (Python 2.4). There
are ways to do it with earlier versions, but everything I've
heard about this (and personal experience with the old way)
suggests you should just use 2.4's subprocess.

What I thought you said is that your C program runs its own
control loop, taking data from stdin and acting on it, presumeably
outputting to stdout if necessary.

Cheers,
Terry
