TCP/IP Sockets in C: Practical Guide for Programmers, 2nd Edition is a quick and affordable way to gain the knowledge and skills needed to develop sophisticated and powerful web-based applications. The book's focused, tutorial-based approach enables the reader to master the tasks and techniques essential to virtually all client-server projects using sockets in C. This edition has been expanded to include new advancements such as support for IPv6 as well as detailed defensive programming strategies.

If you program using Java, be sure to check out this book’s companion, TCP/IP Sockets in Java: Practical Guide for Programmers, 2nd Edition.

Key Features

  • Includes completely new and expanded sections that address the IPv6 network environment, defensive programming, and the select() system call, thereby allowing the reader to program in accordance with the most current standards for internetworking.
  • Streamlined and concise tutelage in conjunction with line-by-line code commentary allows readers to quickly program web-based applications without having to wade through unrelated and discursive networking tenets.
  • Grants the reader access to online source code, which the can then be used to directly implement sockets programming procedures.


Software developers, network programmers, systems programmers, practitioners, researchers who know C and want to learn about writing C networking applications that use TCP/IP, students in courses on computer networking, operating systems, and distributed computing
