If you're trying to determine if a file contains resources (in

Manager APIs, which would be considerably more time consuming.
I don't believe you need to open the file to find out if a file
contains resources.
You can use the BSD function getattrlist. On Tiger you can also the
BSD extended attribute API. See man pages for getattrlist and
listxattr. The extended attribute name for the resource fork is
defined by the constant XATTR_RESOURCEFORK_NAME (defined in /usr/
include/sys/xattr.h).
You can also access resource forks as if they are regular files by
appending "/..namedfork/rsrc" to the name of the file. You may need
to check when this was introduced if you need it to work on older
systems.
