Thanks for the comments!

> Name is really the *path* of the file to open, right?

Correct, it's the path. It might be aelative or absolute. I'll update the docs (but not the variable name).

> What happens to ResultFD if the function fails?

Good point. On Unix it's set to the return value of `open(2)`. I'll double check what happens on Windows and update the docs.
