cocos2dx socket 通信

最近做一个联网实时交互的游戏，游戏中需要使用socket保持长连接，来保证客户端与服务器端进行实时交互。以下贴出自己的一些代码：

因为socket通信部分需要使用多线程，整个流程如下：

1、首先起一个线程，来进行socket通信的连接

int GameServer::connectThreadStart(){
//    connect(GAMESERVER, CCString::create(GAMESERVER_PORT)->intValue());
    
    int errCode = 0;
    do{
        pthread_attr_t tAttr;
        errCode = pthread_attr_init(&tAttr);
        
        CC_BREAK_IF(errCode!=0);
        
        errCode = pthread_attr_setdetachstate(&tAttr, PTHREAD_CREATE_DETACHED);
        
        if (errCode!=0) {
            pthread_attr_destroy(&tAttr);
            break;
        }
        
        errCode = pthread_create(&m_gameThread, &tAttr, connectSocket, this);
        
    }while (0);
    return errCode;
}

2、连接socket代码：

void* GameServer::connectSocket(void* args)
{
    connect(192.168.1.2, 3343);
    return NULL;
}

int GameServer::connect(const char* ip, unsigned int port)
{
    CCLOG(Client begin connect IP: %s:%d ,ip,port);
    struct sockaddr_in sa;
    struct hostent* hp;
    
    hp = gethostbyname(ip);
    if(!hp){
        return -1;
    }
    memset(&sa, 0, sizeof(sa));
    memcpy((char*)&sa.sin_addr, hp->h_addr, hp->h_length);
    sa.sin_family = hp->h_addrtype;
    sa.sin_port = htons(port);
    
    m_socketHandle = socket(sa.sin_family, SOCK_STREAM, 0);
    
    if(m_socketHandle < 0){
        printf( failed to create socket
 );
        return -1;
    }
    if(::connect(m_socketHandle, (sockaddr*)&sa, sizeof(sa)) < 0){
        printf( failed to connect socket
 );
        ::close(m_socketHandle);
        return -1;
    }
    
    CCLOG(Client connect OK ！ IP: %s:%d ,ip,port);

    MTNotificationQueue::sharedNotificationQueue()->postNotification(connectok, NULL);
    return 0;
}

void GameServer::initReceiveThread(CCObject* obj)
{
    int errCode = 0;
    pthread_attr_t tAttr;
    errCode = pthread_attr_init(&tAttr);
    
    errCode = pthread_attr_setdetachstate(&tAttr, PTHREAD_CREATE_DETACHED);
    
    if (errCode!=0) {
        pthread_attr_destroy(&tAttr);
    }else{
        errCode = pthread_create(&m_gameThread, &tAttr, listenSocketData, this);
    }
    if(errCode == 0){
        CCLOG(Receive Thread OK!!!);
    }else{
        CCLOG(Receive Thread Error!!!!);
    }
    
    MTNotificationQueue::sharedNotificationQueue()->postNotification(jointable, NULL);
}
