This book includes enough easy to read explanations of actual working code that you can within a few hours have a client/server socket connection up and working. Both the text and the code are well written and easy to follow. Advanced information about non-blocking I/O allowed me to quickly implement background socket reads without tying up a foreground process. The annoying occurrences of
