DIR(5)                  GENIX Programmer's Manual                  DIR(5)



      NAME
           dir - format of directories

      SYNOPSIS
           #include <sys/types.h>
           #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  fil-
           sys(5).   The structure of a directory entry as given in the include
           file is:

                #ifndef DIRSIZ
                #define DIRSIZ    14
                #endif
                struct  direct
                {
                        ino_t     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 " .}S 3 1 "(" "
           "/"" "" "),"" "" "" where `..' has the same meaning as `.'.
