Exactly, that's why I called it "parent"; but I'm not fussed about the
name, "dir" or "containing_dir" would work as well. I'd just not call
it "filename" as that would be confusing -- this is *not* the file
name of fd, but the directory it lives in (i. e. fd's "parent" if you
will).

I'll look into making these more like open*_at() tomorrow.

Martin
