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
