Client-Side Sockets

IO::Socket greatly simplifies the implementation of a socket for client communications. The following example creates an Internet-domain socket (using the INET subclass) and attempts to connect to the specified server:

use IO::Socket;
$sock = new IO::Socket::INET (PeerAddr => 'www.ora.com',
                              PeerPort => 80,
                              Proto    => 'tcp');
die "$!" unless $sock;

IO::Socket::INET::new creates an object containing a socket filehandle and connects it to the host and port specified in PeerAddr and PeerPort. The object $sock can then be written to and read from like other socket filehandles.
