As mentioned previously, Winsock is available in two major versions—Winsock 1 and Winsock 2—on all Windows platforms except Windows CE (Windows CE has only Winsock 1). When developing new applications you should target the Winsock 2 specification by including WINSOCK2.H in your application. For compatibility with older Winsock applications and when developing on Windows CE platforms, WINSOCK.H is available. There is also an additional header file: MSWSOCK.H, which targets Microsoft-specific programming extensions that are normally used for developing high performance Winsock applications, which will be described in Chapter 6. |
