How we did it:
W. Richard Stevens
A practical book that explains many of the details that have been considered a mystery, this guidebook focuses on the design, development, and coding of networking software under the UNIX operating system. It begins by showing how a fundamental basic for networking programming is interprocess communication (IPC), and a requisite for understanding IPC is a knowledge of what constitutes a process. Throughout, the text provides both a description and examples of how and why a particular solution is arrived at.
