[ast-developers] Directory walker API which takes directory fd as input?

[Lionel Cons]

Does libast have a directory walker API which can take a directory fd
(for openat()) as input to define the starting point?

no -- that's a good point
we would probably add fts_openat(path, fd, flags, comparf)
and extend the *at() semantics to allow path==0 to use fd already in hand

If you do so please include Olga Kryzhanovska's patch from
http://lists.research.att.com/pipermail/ast-developers/2012q3/001777.html
to pass the cwd directory fd to the libcmd builtins.

BTW: Such code should avoid using |chdir()| (no longer being needed
with the |*at()| API) and use |readdir_r()| to make the code fully
thread-safe...

Erm... AFAIK you mean path=="." in this case ?
