Winsock Programmer’s FAQ: Information for New Winsockers. 2.1 - Which sockets API should I target?
From the programmer’s standpoint, there are two major versions of Winsock, 2.0 and 1.1. These are the version numbers you pass to WSAStartup(), and your choice affects whether you #include <winsock2.h> and link against ws2_32.dll or you #include <winsock.h> and link against wsock32.dll. You could choose to declare your program as using some other minor version, but unless you know for a fact that you need to use something different, I recommend using only 1.1 or 2.0, for best compatibility.
The Winsock design is a series of additions to older technologies, not something wholly new. Winsock 2.0 is mostly a strict superset of Winsock 1.1, and Winsock 1.1 is mostly a strict superset of BSD Sockets. The older APIs are still quite useful. The Winsock 1.1 specific DLLs are still provided on the newest versions of Windows. Likewise, BSD Sockets, though a very old API now, still contains a large amount of functionality. Yes. Absolutely!
