opendir
Opens a directory for reading via a directory handle.
Associates a directory handle with the named directory. The
handle can then be used with readdir, rewinddir, seekdir,
telldir, and closedir. All directory entries (including .
and ..) are loaded eagerly into a Vec at open time.
The directory handle variable receives a numeric ID stored in the
global DIRHANDLE_TABLE. Both lexical (my $dh) and bareword
(DH) forms are supported.
Returns 1 on success, undef on failure.
Synopsis
