IO::Socket::UNIX

NAME

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

SYNOPSIS

  1.     use IO::Socket::UNIX;
  3.     my $SOCK_PATH = "$ENV{HOME}/unix-domain-socket-test.sock";
  5.     # Server:
  6.     my $server = IO::Socket::UNIX->new(
  7.         Type => SOCK_STREAM(),
  8.         Local => $SOCK_PATH,
  9.         Listen => 1,
  10.     );
  12.     my $count = 1;
  13.     while (my $conn = $server->accept()) {
  14.         $conn->print("Hello " . ($count++) . "\n");
  15.     }
  17.     # Client:
  18.     my $client = IO::Socket::UNIX->new(
  19.         Type => SOCK_STREAM(),
  20.         Peer => $SOCK_PATH,
  21.     );
  23.     # 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.

    1.     Type    	Type of socket (eg SOCK_STREAM or SOCK_DGRAM)
    2.     Local   	Path to local fifo
    3.     Peer    	Path to peer fifo
    4.     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
