lib:DirHandle

See the current Perl documentation for lib:DirHandle.

Here is our local, out-dated (pre-5.6) version:


DirHandle - supply object methods for directory handles



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

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.
