That sounds to me more like whatever is using IDL happens to provide a discovery service to enquire about the interface and not something fundamental to DCE's lower-level IDL itself. > I was hoping that there would be more than just MS tools that could do > this kind of thing, or at least compile an IDL file to check for > errors. I'll have a look at your other links tomorrow.

I've not used those IDEs but DCE/RPC has been unpopular on Unix since before they came along so I doubt they've the (Windows' specific?) interrogation you're after. > How do Linux programmers write function calls? Purely from the Docs? Yep. The fine man pages traditionally. Supplemented by books, other source code that uses them, and the function call source itself. I wouldn't expect an IDL to be able to describe all the semantics of an interface so even if some whizzy MS GUI lets you inspect it and see what you can poke, you may only be playing all the right notes but not necessarily in the right order.
