NAME
IO::Socket::UNIX - Object interface for AF_UNIX domain socketsSYNOPSIS
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 theAF_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 listenIf 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
