Hello Brian, Thanks for your reply
In fact, I wanna create a pool of connections in order
to read articles from one of these, like this :
sub create_connections {
for (my $i = 1 ; $i <= $max_connections ; $i++) {
$all_connections[$i] =
News::NNTPClient->new($best_ip, $port, $debug);
if ($user) { $all_connections[$i]->authinfo($user,
$password); };
$free_connections[$i] = 1;
}
}
So when I want to read an article, I want to get the
first free connection, but I dont succed in shared
this array
Sorry about but I didnt understand explaination about
'bless' and &share([]) prototyping because I'm a
beginner
Thanks a lot,
Bobby
