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


SEE ALSO

       Socket(3), IO::Socket(3)
