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 socketsin the AF_UNIX domain. It is built upon the IO::Socket interface andinherits all the methods defined by IO::Socket. 

CONSTRUCTOR

new ( [ARGS] )
Creates an "IO::Socket::UNIX" object, which is a reference to anewly 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 tobe a "Peer" specification.

If the "Listen" argument is given, but false, the queue size will be set to 5.

 

METHODS
