This book presents all the skills and techniques needed to become a TCP/IP programmer in a Windows environment.

This book eliminates the obscurity surrounding the Windows Sockets API (Application Programming Interface) with step-by-step explanations and a wealth of sample C programs -- both in the book and on the accompanying disk. There is a heavy emphasis on the tools and techniques needed to design industrial-strength, non-trivial applications. The book also includes coverage of TCP/IP LAN traces used in debugging Winsock applications. and UNIX programmers porting applications to the Windows environment.
