Correct. But none of this is needed in this case. If the function
GetCursorInfo() (for example) is not supported on NT4, then the
attempt to load its function pointer with
cursor = (GETCURSORINFO) GetProcAddress(user,"GetCursorInfo");
will fail. This is the only type of runtime check that is needed.
It doesn't matter if the OS is Win95, NT4, or even Win2000 if the
function pointer cannot be loaded.
