DIR(4)               INTERACTIVE UNIX System               DIR(4)



          NAME
               dir - format of directories

          SYNOPSIS
               #include <sys/dir.h>

          DESCRIPTION
               A directory behaves exactly like an ordinary file, save that
               no user may write into a directory.  The fact that a file is
               a directory is indicated by a bit in the flag word of its
               inode entry [see fs(4)].  The structure of a directory entry
               as given in the include file is:

                    #ifndef DIRSIZ
                    #define DIRSIZ        14
                    #endif
                    struct  direct
                    {
                            ushort      d_ino;
                            char  d_name[DIRSIZ];
                    };

               By convention, the first two entries in each directory are
               for . and ...  The first is an entry for the directory
               itself.  The second is for the parent directory.  The mean-
               ing of .. is modified for the root directory of the master
               file system; there is no parent, so .. has the same meaning
               as ..

          SEE ALSO
               fs(4).

          CAVEAT
               dir(4) may not be compatible with future UNIX systems.  It
               is recommended that you use dirent(4).
