This is an optional file system entry-point for file systems which have a
unique id number for every file in the file system.  It is used
internally by the UFS file system and also by the NFSv3 server to
implement the
.Dv READDIRPLUS
nfs call.
.Pp
If the file system does not support this call, then it should return
.Er EOPNOTSUPP .
