singular hard links

When I do:
touch /tmp/a1
ln /tmp/a1 /tmp/a2
rm /tmp/a2

I get a hard link with a link count (NSFileReferenceCount) of 1.

When I do:
touch //tmp/b1

I get a normal file which also has a link count of 1.

Why should I care? Well, firstly because I am curious, and also: -[NSDocument writeWithBackupToFile: ofType:saveOperation: NSSaveOperation ] fails for singular hard links.

So I would like to detect this case beforehand.


Kind regards,

Gerriet.
