=head1 NAME

IO::Socket::INET - Object interface for AF_INET domain sockets

=head1 SYNOPSIS

use IO::Socket::INET;

=head1 DESCRIPTION

C<IO::Socket::INET> provides an object interface to creating and using sockets
in the AF_INET domain. 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.  If the C<Listen> argument is given, but false,
the queue size will be set to 5.

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',
