Chapter 6 Beyond Basic Socket Programming

Our client and server examples demonstrate the basic model for socket programming. The next step is to integrate these ideas into various programming models such as multitasking, signalling, and broadcasting. We demonstrate these principles in the context of standard UNIX programming; however, most modern operating systems support similar features (e.g., processes and threads).

6.1 Socket Options

The TCP/IP protocol developers spent a good deal of time thinking about the default behaviors that would satisfy most applications. (If you doubt this, read RFCs 1122 and 1123, which describe in excruciating detail the recommended behaviors—based on years of experience—for implementations of the TCP/IP protocols.) ...
