Methods

connect

connect(string host, int port) -> TcpStream | None

Open a real connection to a host and port.

Parameters

host

The host name or address.

port

The port number.

Returns

The connected stream, or None when the connection fails.

Examples

SystemNet net = SystemNet();
TcpStream? s = net.connect("127.0.0.1", 1);
console.writeln(s == None);

true

listen

listen(int port) -> TcpListener

Start listening on a real port.

Port 0 lets the system choose a free port. The caller checks ok() on the result to see whether the port could be bound, and calls stop() when done.

Parameters

port

The port number to listen on.

Returns

The listener.

Examples

SystemNet net = SystemNet();
TcpListener l = net.listen(0);
console.writeln(l.ok());
l.stop();
