It is built upon the L<IO::Socket> interface and -inherits all the methods defined by L<IO::Socket>. - -=head1 CONSTRUCTOR - -=over 4 - -=item new ( [ARGS] ) - -Creates an C<IO::Socket::INET> object, which is a reference to a -newly created symbol (see the C<Symbol> package). C<new> -optionally takes arguments, these arguments are in key-value pairs. - -In addition to the key-value pairs accepted by L<IO::Socket>, -C<IO::Socket::INET> provides. - - - PeerAddr Remote host address <hostname>[:<port>] - PeerHost Synonym for PeerAddr - PeerPort Remote port or service <service>[(<no>)] | <no> - LocalAddr Local host bind address hostname[:port] - LocalHost Synonym for LocalAddr - LocalPort Local host bind port <service>[(<no>)] | <no> - Proto Protocol name (or number) "tcp" | "udp" | ... - Type Socket type SOCK_STREAM | SOCK_DGRAM | ... - Listen Queue size for listen - ReuseAddr Set SO_REUSEADDR before binding - Reuse Set SO_REUSEADDR before binding (deprecated, prefer ReuseAddr) - ReusePort Set SO_REUSEPORT before binding - Broadcast Set SO_BROADCAST before binding - Timeout Timeout value for various operations - MultiHomed Try all addresses for multi-homed hosts - Blocking Determine if connection will be blocking mode - -If C<Listen> is defined then a listen socket is created, else if the -socket type, which is derived from the protocol, is SOCK_STREAM then -connect() is called. - -Although it is not illegal, the use of C<MultiHomed> on a socket -which is in non-blocking mode is of little use. This is because the -first connect will never fail with a timeout as the connect call -will not block. - -The C<PeerAddr> can be a hostname or the IP-address on the -"xx.xx.xx.xx" form. The C<PeerPort> can be a number or a symbolic -service name. The service name might be followed by a number in -parenthesis which is used if the service is not known by the system. -The C<PeerPort> specification can also be embedded in the C<PeerAddr> -by preceding it with a ":". - -If C<Proto> is not given and you specify a symbolic C<PeerPort> port, -then the constructor will try to derive C<Proto> from the service -name. As a last resort C<Proto> "tcp" is assumed. The C<Type> -parameter will be deduced from C<Proto> if not specified. - -If the constructor is only passed a single argument, it is assumed to -be a C<PeerAddr> specification. - -If C<Blocking> is set to 0, the connection will be in nonblocking mode. -If not specified it defaults to 1 (blocking mode). - -Examples: - - $sock = IO::Socket::INET->new(PeerAddr => 'www.perl.org', - PeerPort => 'http(80)', - Proto => 'tcp'); - - $sock = IO::Socket::INET->new(PeerAddr => 'localhost:smtp(25)'); - - $sock = IO::Socket::INET->new(Listen => 5, - LocalAddr => 'localhost', - LocalPort => 9000, - Proto => 'tcp'); - - $sock = IO::Socket::INET->new('127.0.0.1:25'); - - $sock = IO::Socket::INET->new(PeerPort => 9999, - PeerAddr => inet_ntoa(INADDR_BROADCAST), - Proto => udp, - LocalAddr => 'localhost', - Broadcast => 1 ) - or die "Can't bind : $@\n"; - - NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE - -As of VERSION 1.18 all IO::Socket objects have autoflush turned on -by default. This was not the case with earlier releases. - - NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE - -=back - -=head2 METHODS - -=over 4 - -=item sockaddr () - -Return the address part of the sockaddr structure for the socket - -=item sockport () - -Return the port number that the socket is using on the local host - -=item sockhost () - -Return the address part of the sockaddr structure for the socket in a -text form xx.xx.xx.xx - -=item peeraddr () - -Return the address part of the sockaddr structure for the socket on -the peer host - -=item peerport () - -Return the port number for the socket on the peer host. - -=item peerhost () - -Return the address part of the sockaddr structure for the socket on the -peer host in a text form xx.xx.xx.xx - -=back - -=head1 SEE ALSO - -L<Socket>, L<IO::Socket> - -=head1 AUTHOR - -Graham Barr.
