Question

I’ve got a TCP socket which reads data. When an error occurs when reading the data, I return an undef (NULL) value. Errors can be caused by badly formatted messages or broken sockets. Can someone tell me if there is a specific function which returns the status of a socket?

doh!, the answer was obvious in retrospect, use the connected call.

$socket = IO::Socket::INET(localhost, 1000);
die "no connection" unless $socket -> connected();
$socket -> send("your face here for $20");
die "socket is dead" unless $socket -> connected();
$socket -> recv($data);
