     NAME
          inode - format of a System V inode

     SYNOPSIS
          #include <sys/types.h>

     DESCRIPTION
          An inode for a plain file or directory in a file system has
          the following structure defined by <svfs/inode.h>.

          /* Inode structure as it appears on a disk block. */
          struct    dinode {

                  ushort  di_mode;     /* mode and type of file */
                  short   di_nlink;    /* number of links to file */
                  ushort  di_uid;      /* owner's user ID */
                  ushort  di_gid;      /* owner's group ID */
                  off_t   di_size;     /* number of bytes in file */
                  char    di_addr[40]; /* disk block addresses */
          #define di_gen; di_addr[39]
                  time_t  di_atime;    /* time last accessed */
                  time_t  di_mtime;    /* time last modified */
                  time_t  di_ctime;    /* time created */
          };

          /*
          * the 40 address bytes:
          *    39 used; 13 addresses
          *    of 3 bytes each.
          */
