DIR(F)                                     UNIX System V



     Name
          dir - format of a directory


     Syntax
          #include <sys/dir.h>


     Description
          A directory behaves exactly like an  ordinary  file,  except
          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 filesystem(F)).  The structure of a
          directory    is    given     in     the     include     file
          /usr/include/sys/dir.h.

          By convention, the  first  two  entries  in  each  directory
          are``dot''  (.)  and  ``dotdot'' (..). The first is an entry
          for the directory itself.  The  second  is  for  the  parent
          directory.   The  meaning of dotdot is modified for the root
          directory of the master file system; there is no parent,  so
          dotdot has the same meaning as dot.
