Well, your documentation is for Windows CE (look at the bottom of the page).
Here is the documentation for Windows 95 to Windows Vista:
http://msdn.microsoft.com/en-us/library/ms741580(VS.85).aspx

And there you can find the following sentences: "If a function call's return
value indicates that error or other relevant data was returned in the error
code, WSAGetLastError should be called immediately. This is necessary because
some functions may reset the last extended error code to 0 if they succeed,
overwriting the extended error code returned by a previously failed function."
