VC++ 6.0
Windows XP (Home)

I was just tinkering around with the NetUserGetInfo() function.
According to the MSDN docs, if you pass 23 as a level, you get back a
USER_INFO_23 structure. However, looking in my lmaccess.h file, I
don't possess such a structure (and attempting to reference it causes
a build error). The closest I see is USER_INFO_22, which is a
substantially different structure.

According to the MSDN site, USER_INFO_23 is supported on Windows XP.
Is USER_INFO_23 only in later versions of VC++? What am I missing?
