        uid_t   uid;                  /* owner's user id           */
        gid_t   gid;                  /* owner's group id          */
        uid_t   cuid;                 /* creator's user id         */
        gid_t   cgid;                 /* creator's group id        */
        long    mode;                 /* access modes              */
        long    seq;                  /* slot usage sequence number*/
        key_t   key;                  /* key                       */
