Hi all
Would someone be so kind to explain the following code.
my $subclasses = { 'rejects' => \&_reject_html,
'deferrals' => \&_deferral_html,
'errors' => \&_error_html,
'deliveries' => \&_delivery_html,
'unknown' => \&_unknown_html,
'queue' => \&_queue_html };
The following code comes from the Tom Kistner's exilog
(http://duncanthrax.net/exilog/).
Would someone please share some info on why \& and not just &?
When do you use this?
Thanks in advance.
Brent Clark
