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
