I invented my own in rosh after not having one in the libraries based
on what I thought was the most reasonable use of existing functions.

Yes, that's what I mentioned, but I can't find it in the library
modules, only in rosh.elf.  Or maybe I didn't get your point.  Could you
elaborate, please?

On the other hand, your implementation (as well as mine) calls open()
and opendir() to identify files and directories.  That more or less
works for everyday purposes (and FAT filesystems), but I wonder whether
there's more available power in dirent() in other filesystem drivers.
Maybe a searchdir()-based stat() implementation would be better from all
aspects, but I don't know enough about the internals to judge.
