RE: [ECOS] opendir with empty directory name?

This is the client code.  I agree with you that we should use "." for
the currdir to avoid this non portable behavior.

Why not just use the POSIX standard path (".") and *not* rely on
[possibly] non-standard behaviour.

If you've seen other code that uses "" to mean the current directory,
I'd postulate that code is incorrect or at the very least, non portable.
Was this eCos code?  in CVS or elsewhere?
