IO::Socket::UNIX - phpMan

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.

        If the constructor fails it will return "undef" and set the
        $IO::Socket::errstr package variable to contain an error message.

            $sock = IO::Socket::UNIX->new(...)
                or die "Cannot create socket - $IO::Socket::errstr\n";

        For legacy reasons the error message is also set into the global $@
        variable, and you may still find older code which looks here
        instead.

            $sock = IO::Socket::UNIX->new(...)
                or die "Cannot create socket - $@\n";

METHODS
    hostpath()
        Returns the pathname to the fifo at the local end

    peerpath()
        Returns the pathanme to the fifo at the peer end
