dll ignorance

[Mark Paris]

Ok, I'll admit it, I am utterly ignorant of how to use a .dll with Rev.  Can
someone enlighten me on this?

Let's say I have a dll that contains a function, let's say it adds x+y and
returns the result.  So how do I call that function from the Rev program?
Is this a fairly simple thing to do?  Can I pass x and y from Rev to the dll
and get an answer back into Rev?  How do I tell Rev to use the dll?

Thanks very much for any insight!
