I've written a "server" of sorts that does the bulk work of the processing. The app is written in VC++ and IS a GUI app.

What I'd like to do is leave some "hooks" in the EXE to allow "clients" to access the functions. The client will be running on the same PC that the server would.

My question is, how would I:

(a) define a function that can be called from another process?
(b) how would I call it from a dll?

Thanks for any assistance!
