Thanks everyone for your quick and helpful responses. This is exactly what I was hoping for.
Robert, I'm looking for background information rather than specific capability at this stage. Alan, thanks for the very detailed reply. I am working with C++, and the book you recommended looks like a perfect way to get up to speed on some of the detail. Thomas, Theo, David, thank you all, I feel that I have very quickly acquired some good direction!
