I was exploring the qnx environment when I noticed that ls's ln field for directories was >1.  I thought that was 
strange and I attempted to find where the other link was.  I used find's -inode and a combination of find, xargs, ls, 
sort and awk for good measure. Turns out there wasn't any.

So my question is, what is the ln field representing for a directory?

Thx.
