It's not encouraged to create them (they're never created on non-Time Machine volumes), and it's not possible to create them except as root.

I took a quick glance at getattrlist(2) and didn't see this value exported, so I'm guessing it's not (easily) available.

OS-X 10.5 now allows you to hard link directories.

However the link count of the directory seems to behave in the conventional unix way. i.e. it is the number of directories contained in that directory + 2 for "." and "..".

Is there a way to find out the link count for directories, or to otherwise discover if a particular directory has hard links?
