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 in-
dicated 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 re-
movable 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 `.'.
