Binding a server-side socket to a specific adaptor? Any socket gurus out there?

Our servers, up to now, have been binding the server socket with

> localAddr.sin_addr.s_addr = INADDR_ANY

We now have a customer who wants to be able to bind to a specific adaptor, and quite honestly, I'm not sure how the bind works with the above fragment, let alone how to bind it to a specific adaptor.

I'm guessing that binding to INADDR_ANY sets it up to accept any connection that comes in with the right port number. Am I at least correct here?

Given a dotted-decimal address for where the socket should be accepting connections, what would I do to put it into localAddr.sin_addr.s_addr?
