NFS and readdir

Hi group

I am having some troubles with readdir on a NFS mounted
directory and I hope that someone here can help me.

The mounted directory is a directory of another iSeries computer,
and it has (so far) worked fine.

I am trying to list the contents of the directory using opendir() and
readdir(). The opendir() returns an pointer, as it should (I don't know
if it is correct). But when I use the readdir() it returns the *null
pointer.

When I use the same program on an IFS directory it works fine !

In another program I use the stat() api on the same NFS mounted directory
without any errors.

Thanks in advance
Lars
