  Mac OS X allows accessing resource forks of files (at least on
native HFS(+) partitions) by appending "/rsrc" to the file name
(e.g. /path/to/file/rsrc).  (BTW, NetBSD's HFS+ implementation does,

  The advantage of this over a separate API is that subfile-ignorant
tools can access subfiles (although they cannot list them).


PS: As far as I know, previous versions of Mac OS did allow access to
the resource fork only via the resource manager, not as a byte
