[ Version ( since = "2.22" ) ]
public class ThreadedSocketService : SocketService

Example: Threaded socket service:

Note:

Use telnet localhost 1024 or telnet localhost 1025 to create connections

Note:

Send "shutdown" to close the server.

public class Source : Object {
public uint16 port { private set; get; }

public static int main (string[] args) {

try {
// Listen on port 1024 and 1025.
// Source is used as source-identifier.
service.add_inet_port (1024, new Source (1024));

// Used to shutdown the program:
Cancellable cancellable = new Cancellable ();
cancellable.cancelled.connect (() => {

// The run signal is emitted in a worker thread:
service.run.connect ((connection, source_object) => {

// Response:
ostream.put_string (message, cancellable);
ostream.put_byte ('\n', cancellable);
