  DIR(4)                                                     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
       i-node 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
       meaning of .. is modified for the root directory of the
       master file system; there is no parent, so .. has the same
       meaning as ..

  SEE ALSO
