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.
