Query: Good beginner's book, but brief.

On the positive side, this book is an excellent entry-level programmer's guide to the SDL library. Anybody with basic coding skills should be able to easily follow the examples (which, by the way, are not duplicated in print... something to keep in mind if you are reading this on the train). Surely you could learn all you need to from SDL's own web site and other online documentation. But if you prefer to sit down and read a book cover to cover, like I do, this book might be a better fit.My biggest disappointment is that there is no coverage of OpenGL at all. My attraction to SDL is to use as a base platform for OpenGL coding. A chapter on OpenGL integration would have won a fifth star from me.I would like to have seen more advanced and in-depth coverage. Maybe another chapter or so on implementing an example game using the framework given to us in the final section.
