Communicating with a DLL

I have an LSP (Layered Service Provider) DLL, but once it's installed in the catalog, how to i communicate with it in my program? My LSP is based largely off of Microsoft's sample LSP.

I was reading komodia's write up on LSP DLL's and they state that you need IPC(intern Process Communicatio开发者_Python百科n) via mail slots, named pipes, COM, etc.

Im having trouble accumulating more info regarding this. What is the best, most efficient way to communicate with my LSP DLL as it operates on the catalog?

Thanks.
