DIR(5)                        File Formats Manual                       DIR(5)



NAME
       dir - format of directories

SYNOPSIS
       #include <&lt;sys/dir.h>&gt;

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, filsys(5).
       The structure of a directory entry as given in the include file is:

       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 and for the root directories of
       removable file systems.  In the first case, there is no parent, and  in
       the  second,  the system does not permit off-device references.  There-
       fore in both cases `..' has the same meaning as `.'.
