IO::Dir(3pm)			 Perl Programmers Reference Guide		     IO::Dir(3pm)

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,"\n";
	   }

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 created. Assigning a single integer to a HASH
       element will cause both the access and modification times to be changed to that value.
       Alternatively 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 element will be used to set the modifi-
       cation time.
