To Write WinSock Programs

If you’re a Windows C or C++ programmer, you probably already have everything you need to use and program for WinSock. Most commercial Windows C and C++ compilers provide the needed header files and import libraries.

There are currently three distributions of WinSock header and library files. Note that WinSock has maintained backwards compatibilibty. Programs linked with WinSock 1.1 will still run on WinSock 2.
