is the location identifier.
link_name specify the location and name, respectively, of the new soft link.
link_name is interpreted relative to
link_loc_id and must contain only the name of the soft link;
link_name may not contain any additional path elements.
link_loc_id is a group identifier, the object pointed to by
link_name will be accessed as a member of that group. If
link_loc_id is a file identifier, the object will be accessed as a member of the file’s root group.
lapl_id are the link creation and access property lists associated with the new link.
For instance, if
./x/y/bar, and the name of the new link is
new_link, then a subsequent request for
./x/y/bar/new_link will return same the object as would be found at
