Could someone help me understand what I'm missing in trying to get a
simple socket server running?
Thanks,
reid
using GLib;
class ServerDemo {
public static GLib.MainLoop loop;
bool handler(SocketConnection connection, GLib.Object source) {
var dis = new DataInputStream (connection.input_stream);
var dos = new DataOutputStream(connection.output_stream);

SocketService server = new SocketService();

I managed to get a simple threaded example working, but would appreciate
any input as to things that may be incorrect, or that could be
implemented better....
using GLib;
// using Timeout;
bool
handler(SocketConnection connection, GLib.Object source_object) {
var dis = new DataInputStream (connection.input_stream);
var dos = new DataOutputStream(connection.output_stream);
connection.socket.set_blocking(true);
string message = dis.read_line(null,null).strip();
stdout.printf("message[%s]\n", message);
try {
dos.put_string("back at you: " + message, null);
} catch (Error e) {
stderr.printf("%s\n", e.message);
}
return(true);
}
class ServerDemo {
public static GLib.MainLoop loop;
public void run () throws Error {
ThreadedSocketService server = new ThreadedSocketService(3);
server.add_inet_port(7500, server);
server.run.connect(handler);
}
public static int main (string[] args) {
loop = new GLib.MainLoop(null, false);
try {
new ServerDemo().run ();
} catch (Error e) {
stderr.printf ("%s\n", e.message);
