Lacewing Build #19

I've got yet another question:
How do I start a new thread in the new Lacewing? In build #17 I had a line:

Code:

---

Lacewing::Utility::StartThread(ping, &Server);

---

And what's the difference between starting a thread in Lacewing and starting a thread in C/C++?

The thread functionality is a class now:

Code:

---

Lacewing::Thread MyThread ("Some Name", YourThreadFunction);
MyThread.Start (SomeParameter);

---

The difference is that C/C++ has no facility for starting threads. Lacewing uses whatever functionality is provided by the operating system (WINAPI, or pthread on Unix).

I hope you're aware that most of the liblacewing classes aren't thread safe! Maybe you should consider using something like Lacewing::Timer (if possible) rather than a thread. Failing that, use the EventPump Post() method to run code at a safe time in Lacewing's event loop.

Thanks for the quick reply, as always :D

I had no idea, thanks for letting me know :) You mean something like this?

Code:

---

void onTick (Lacewing::Timer &Timer)
{
  //Ping all clients
}

Lacewing::EventPump TimerPump;
Lacewing::Timer Timer(TimerPump);
Timer.onTick(onTick);
Timer.Start(30000);

---

To ping each 30 seconds?

Both the Server and the Timer should share the same EventPump, but otherwise, yes.

Did you know that the protocol has pinging built in to detect lost connections?

Really? :D Is that some class I need to use or is pinging done automatically?

It's automatic!

By the way, the correct usage of the EventPump in a console application:

Code:

---

int main (int argc, char * argv [])
{
    Lacewing::EventPump EventPump;

    /* Create any classes you want to use, passing EventPump to the constructor.  Example: */

    Lacewing::RelayServer Server (EventPump);
    Server.Host ();

    /* This function will not return.  Internally, it will loop forever,
      letting the other classes know when a socket is ready etc. */

    EventPump.StartEventLoop ();

    return 0;
}

---

Wow, that's great! :D Lacewing keeps surprising me :D
And thanks for the code sample :D

Sorry for bothering, but I've got YET another question xD
Could you please give me a sample code on how to iterate through all clients in the server/channel?

No bother at all! :-)

Iterating through all clients on the server:

Code:

---

for (Lacewing::RelayServer::Client * Client = Server.FirstClient ();
                Client; Client = Client->Next ())
      {
          printf ("Client %s is present\n", Client->Name ());
      }

---

Iterating through all clients on a channel:

Code:

---

Lacewing::RelayServer::Channel::ClientIterator Iterator (Channel);

for (Lacewing::RelayServer::Client * Client = Iterator.Next ();
            Client; Client = Iterator.Next ())
    {
        printf ("Client %s is in the channel\n", Client->Name ());
    }

---

If you get any "unresolved external symbol" errors with this code, grab the edge liblacewing source from here.

Thanks again! :D I'm sure it's gonna be helpful, not only for me :D

EDIT:
I had the "unresolved external" problem and compiled the source you gave me and it compiled correctly. Do I need to use that *.DLL too?

Sorry for the double post, but it's a different thing now. There seems to be a bug in the Relay Client for MMF. The function "StringWithSize$" takes only one parameter - the index. Shouldn't it also take the size?
