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
