DirHandle(3)

NAME
     DirHandle - supply object methods for directory handles

SYNOPSIS
         use DirHandle;
         $d = new DirHandle ".";
         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.
