NAME

       DirHandle - supply object methods for directory handles

SYNOPSIS

	   use DirHandle;
	   $d = DirHandle->new(".");
	   if (defined $d) {
	       while (defined($_ = $d->read)) { something($_); }
	       $d->rewind;
	       while (defined($_ = $d->read)) { something_else($_); }
	       undef $d;
	   }

DESCRIPTION

       The "DirHandle" method provide an alternative interface to the opendir(), closedir(), readdir(), and rewinddir() functions.

       The only objective benefit to using "DirHandle" is that it avoids namespace pollution by creating globs to hold directory handles.

NAME

       IO::Dir - supply object methods for directory handles

SYNOPSIS

	   use IO::Dir;
	   $d = new IO::Dir ".";
	   if (defined $d) {
	       while (defined($_ = $d->read)) { something($_); }
	       $d->rewind;
	       while (defined($_ = $d->read)) { something_else($_); }
	       undef $d;
	   }

	   tie %dir, IO::Dir, ".";
	   foreach (keys %dir) {
	       print $_, " " , $dir{$_}->size,"
";
	   }

DESCRIPTION

       The "IO::Dir" package provides two interfaces to perl's directory reading routines.

       The first interface is an object approach. "IO::Dir" provides an object constructor and methods, which are just wrappers around perl's
       built in directory reading routines.

       new ( [ DIRNAME ] )
	   "new" is the constuctor for "IO::Dir" objects. It accepts one optional argument which,  if given, "new" will pass to "open"

       The following methods are wrappers for the directory related functions built into perl (the trailing `dir' has been removed from the
       names). See perlfunc for details of these functions.

       open ( DIRNAME )
       read ()
       seek ( POS )
       tell ()
       rewind ()
       close ()

       "IO::Dir" also provides an interface to reading directories via a tied HASH. The tied HASH extends the interface beyond just the directory
       reading routines by the use of "lstat", from the "File::stat" package, "unlink", "rmdir" and "utime".

       tie %hash, IO::Dir, DIRNAME [, OPTIONS ]

       The keys of the HASH will be the names of the entries in the directory.	Reading a value from the hash will be the result of calling
       "File::stat::lstat". Deleting an element from the hash will call "unlink" providing that "DIR_UNLINK" is passed in the "OPTIONS".

       Assigning to an entry in the HASH will cause the time stamps of the file to be modified. If the file does not exist then it will be cre-
       ated. Assigning a single integer to a HASH element will cause both the access and modification times to be changed to that value. Alterna-
       tively a reference to an array of two values can be passed. The first array element will be used to set the access time and the second ele-
       ment will be used to set the modification time.
