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.
-
On Mac OS (Classic), the path separator is ':', not '/', and the
current directory is denoted as ':', not '.'. You should be careful
about specifying relative pathnames. While a full path always begins
with a volume name, a relative pathname should always begin with a
':'. If specifying a volume name only, a trailing ':' is required.
