NAME

       DirHandle - (obsolete) supply object methods for directory handles


SYNOPSIS

           # recommended approach since Perl 5.6: do not use DirHandle
           if (opendir my $d, '.') {
               while (readdir $d) { something($_); }
               rewind $d;
               while (readdir $d) { something_else($_); }
           }

           # how you would use this module if you were going to
           use DirHandle;
           if (my $d = DirHandle->new(".")) {
               while (defined($_ = $d->read)) { something($_); }
               $d->rewind;
               while (defined($_ = $d->read)) { something_else($_); }
           }


DESCRIPTION

       There is no reason to use this module nowadays.

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

       Up to Perl 5.5, opendir() could not autovivify a directory handle from
       "undef", so using a lexical handle required using a function from
       Symbol to create an anonymous glob, which took a separate step.
       "DirHandle" encapsulates this, which allowed cleaner code than
       opendir().  Since Perl 5.6, opendir() alone has been all you need for
       lexical handles.
