IPC between C# app, via native C++ DLL, to another app consuming DLL with embedded Lua?

Question

Basically I'm asking how to implement the same flow as explained here.

I want my C# to supply callbacks to a native C++ DLL that I have written.

I want this DLL to be loaded by the Lua engine that's embedded into another application,
MUSHClient (a MUD/telnet client, with embedded Lua), via package.loadlib("native.dll", "someInitFunction");.

Then in MUSHClient I want to write scripts that call functions exposed by the DLL. I want these functions to call the callback function/delegate supplied by my C# application.

How can I do this?
I know how to export functions in my DLL, what I don't know is how to share the callback between processes.

If you have two processes, you need some form of IPC. What sort of IPC do you want to use? — David Heffernan, Apr 09 '12 at 13:41
Is it possible to use shared memory and share a function pointer for the callback/delegate? — Zolomon, Apr 09 '12 at 13:43

You need some kind of Inter-process communication (IPC).

I'd recommend Named Pipes.

Here is a good example of a named pipe implementation in C# & C++.

How do you use named pipes in native C++ (not C++/CLI)? – Zolomon Apr 09 '12 at 13:56
