NAME

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

CONTENTS

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
