link(2) allows directory hard links, man page says otherwise



The actual implementation of link() on 10.5 allows for directory hard links on HFS+ as long as they follow these rules:

- Source parent and destination parent cannot match
- A link is not permitted in the root directory
- Parent of 'pointed at' directory is not the root directory
- The 'pointed at' directory (source) is not an ancestor of the new directory hard link (destination).
- No ancestor of the new directory hard link (destination) is a directory hard link.


The man page for link(2) says (in various places):

As mandated by POSIX.1, path1 may not be a directory.


[EPERM] The file named by path1 is a directory.


STANDARDS
The link() function is expected to conform to IEEE Std 1003.1-1988 (``POSIX.1'').




But actually calling link() allows for directory hard links. Is this an error in the documentation, an error in the function, or am I connecting two things that shouldn't be?
