[ENet-discuss] help needed for a client/server example

[Schwarzbauer Martin - S0810567019]

Hi !

i'm experimenting with the Enet-Library ... so i tried to write a simple client - server test application.
I also studied the Tutorial page but i don't know how to send/receive data. When the server-app is running, the client can "connect" to the server ("Connection to server succeeded." is displayed).

 Now, how can i send data between server and client, after the client is connected or how does the server know that a client connected?

Server:
if (enet_initialize () != 0)
        {
                fprintf (stderr, "An error occurred while initializing ENet.\n");
                return EXIT_FAILURE;
        }
        atexit (enet_deinitialize);

        ENetAddress address;
        ENetHost * server;
        ENetEvent event;

        /* Bind the server to the default localhost.     */
        /* A specific host address can be specified by   */
        // enet_address_set_host (& address, "localhost");
        address.host = ENET_HOST_ANY;

        /* Bind the server to port 1234. */
        address.port = 1234;

        server = enet_host_create (&address /* the address to bind the server host to */,
                                   1        /* allow up to 32 clients and/or outgoing connections */,
                                   0        /* assume any amount of incoming bandwidth */,
                                   0        /* assume any amount of outgoing bandwidth */);


        if (server == NULL)
        {
                fprintf (stderr,
                                "An error occurred while trying to create an ENet server host.\n");
                  exit (EXIT_FAILURE);
        }
        enet_host_destroy(server);




Client:
if (enet_initialize () != 0)
        {
                fprintf (stderr, "An error occurred while initializing ENet.\n");
                return EXIT_FAILURE;
        }
        atexit (enet_deinitialize);

        ENetAddress address;
        ENetHost * client;
        ENetPeer *peer;
        ENetEvent event;

        /* Connect to localhost:1234. */
        enet_address_set_host (& address, "localhost");
        address.port = 1234;

        client = enet_host_create (NULL /* create a client host                    */,
                                   1    /* allow only 1 outgoing connection        */,
                                   0    /* assume any amount of incoming bandwidth */,
                                   0    /* assume any amount of outgoing bandwidth */);


        if (client == NULL)
        {
                fprintf (stderr,
                                "An error occurred while trying to create an ENet client host.\n");
                  exit (EXIT_FAILURE);
        }

        /* Initiate the connection, allocating one channel */
        peer = enet_host_connect (client, &address, 1);

        if (peer == NULL) {
                fprintf (stderr,
                                "No available peers for initiating an ENet connection.\n");
                enet_host_destroy(client);
                exit (EXIT_FAILURE);

        }

        /* Wait up to 5 seconds for the connection attempt to succeed. */
        if (enet_host_service (client, &event, 5000) > 0 &&
                event.type == ENET_EVENT_TYPE_CONNECT)
        {
                puts ("Connection to server succeeded.");
        }
        else
        {
                /* Either the 5 seconds are up or a disconnect event was */
                /* received. Reset the peer in the event the 5 seconds   */
                /* had run out without any significant event.            */
                enet_peer_reset (peer);

                puts ("Connection to server failed.");
        }

        enet_host_destroy(client);



thx in advance,
Martin

PS: maybe it would be a idea to insert a full server - client - example onto the homepage.
