UNIX Network Programming, Volume 1: The Sockets Networking API (3rd Ed.)

This is THE guide to UNIX network programming APIs. Whether you write Web servers, client/server applications, or any other network software, you need to understand networking APIS-especially sockets in greater detail than ever before. You need UNIX Network Programming, Volume 1, Third Edition. In this book, the Authors offer unprecedented, start-to-finish guidance on making the most of sockets, the de facto standard for UNIX network programming with APIs - as well as extensive coverage of the X/Open Transport Interface (XTI).
