So I took time and submitted a request to update lstrcmpW documentation because it is inaccurate.
It seemed pretty obvious that Syntax section shows W types (correct) and Parameters section shows T types trying to document the same thing. Some articles, for CRT functions specifically, solve this by documenting a set of similar functions at once, but it is not the case here.
The response was a bit unexpected:
Well, good luck with clarity and accuracy in SDK documentation then.
