# NAME

IO::Socket::UNIX - Object interface for AF_UNIX domain sockets

# SYNOPSIS

        use IO::Socket::UNIX;    my $SOCK_PATH = "$ENV{HOME}/unix-domain-socket-test.sock";    # Server:    my $server = IO::Socket::UNIX->new(        Type => SOCK_STREAM(),        Local => $SOCK_PATH,        Listen => 1,    );    my $count = 1;    while (my $conn = $server->accept()) {        $conn->print("Hello " . ($count++) . "\n");    }    # Client:    my $client = IO::Socket::UNIX->new(        Type => SOCK_STREAM(),        Peer => $SOCK_PATH,    );    # Now read and write from $client

# DESCRIPTION

`IO::Socket::UNIX` provides an object interface to creating and using sockets in the AF_UNIX domain. It is built upon the IO::Socket interface and inherits all the methods defined by IO::Socket.

# CONSTRUCTOR

- new ( [ARGS] )

  Creates an `IO::Socket::UNIX` object, which is a reference to a newly created symbol (see the `Symbol` package). `new` optionally takes arguments, these arguments are in key-value pairs.

  In addition to the key-value pairs accepted by IO::Socket, `IO::Socket::UNIX` provides.

          Type    	Type of socket (eg SOCK_STREAM or SOCK_DGRAM)    Local   	Path to local fifo    Peer    	Path to peer fifo    Listen  	Queue size for listen

  If the constructor is only passed a single argument, it is assumed to be a `Peer` specification.

  If the `Listen` argument is given, but false, the queue size will be set to 5.

# METHODS

- hostpath()

  Returns the pathname to the fifo at the local end

- peerpath()

  Returns the pathanme to the fifo at the peer end
