Well, I wouldn't say "makes more sense". It may be more traditional (for
Linux), but it has its problems, notably performance. One use of F_GETPATH
is for server code, to check that a previous open() didn't follow symlinks
to outside of some specified area.
Not that I like F_GETPATH much either, but portability is a strong enough
argument that coming up with some *other* way is probably not great.
