dir(4)                                                     dir(4)



     NAME
          dir - format of System V directories

     SYNOPSIS
          #include <svfs/fsdir.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  SVFSDIRSIZ
             #define  SVFSDIRSIZ   14
             #endif

             struct   svfsdirect {
                      ino_t        d_ino;
                      char         d_name[SVFSDIRSIZ];
             };

          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 ``.''.
