The IO::Dir package provides two interfaces to perls directory reading
The first interface is an object approach. IO::Dir provides an object
constructor and methods, which are just wrappers around perls built in
directory reading routines.
new ( [ DIRNAME ] )
new is the constructor 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 )
seek ( POS )
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
delete the corresponding file or subdirectory,
provided that DIR_UNLINK is included 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 modification
