You're essentially returning a tri-state here, split over two `BOOL`s. It might be better to return an `HRESULT` using `S_OK`, `S_FALSE` and something else to signify a hard mismatch. At the very least expand the comment to explain what the two `BOOL`s mean.

This `if` condition is challenging to decipher. Perhaps it would be simpler comparing `!!name[0]` with `!!name[1]`, or breaking this out into a series of `if` statements.

Err, obviously comparing `!name[0]` directly with `!name[1]` would also work.

Yeah, since wcscmp doesn't handle NULL inputs, I was basically trying to do what lstrcmpW does in a single if statement, i.e:
``` if (!str1 && !str2) return 0; if (!str1) return -1; if (!str2) return 1; ```
but splitting it out into multiple if statement would definitely make things clearer.
