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
