statat(2) doesn't interact with the filename at all, does it? You need to have already opened the file, but it doesn't know or care by what name you opened it, or even if that name still exists.

Unfortunately it does. See "pathname" parameter: int fstatat(int dirfd, const char *pathname, struct stat *statbuf, int flags);

It stats the file "pathname" relative to directory "dirfd". Normally when readdir returns DT_UNKNOWN one has to statat the filename relative to the directory to figure out the real d_type.

Gah, thanks. Looks like I was thinking of BSD.

Are you thinking of fstat(2)?
