If you're talking about doing interprocess communication (IPC) on a
Linux box (I'm teaching this topic right now in my OS course), you
might want to check out one of the Linux newsgroups that has something
to do with kernel programming.

comp.os.linux.development.system

On the Linux side we can use pipes and named pipes, as well as
signals.

For Windows, I'm not too familiar with how IPC works.

FIRST ASK YOURSELF: what information do you want to exchange between
the two processes?

Good luck
