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?

the POSIX standard you reference is outdated. please refer to: http://www.opengroup.org/onlinepubs/009695399/functions/link.html where it quotes: If path1 names a directory, link() shall fail unless the process has appropriate privileges and the implementation supports using link() on directories. and under errors it states: [EPERM] The file named by path1 is a directory and either the calling process does not have appropriate privileges or the implementation prohibits using link() on directories. -mike _______________________________________________ Do not post admin requests to the list.
