This book delivers on its title. I found some of the code useful immediately straight out of the book. I also have his Linux Programming book. It too is very good. I would have given it five stars; but for lack in two areas: firstly, I would have liked coverage of dynamic restart of client / server apps and logging; secondly, as there isn't a CD provided, a download site is given which reroutes you somewhere else and I couldn't find any code to download. This also occured for my other SAMS book by the same author.
