DirHandle - supply object methods for directory handles
use DirHandle; $d = DirHandle->new("."); 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.
DirHandle
The only objective benefit to using DirHandle is that it avoids namespace pollution by creating globs to hold directory handles.
