Question

我正在尝试通过成员函数进行线程调用。问题是我在同一个类的另一个成员函数内进行调用。我的意思是：

class A {
   void foo(int a);

   void bar() {
       int k = 2;
       thread t(&A::foo, this, k);
   }
}

我还尝试将this作为参考传递：&this或std::ref(this)但没有成功。究竟是什么错误？

编辑：以下是给出错误的实际代码

class SUBTHREAD {
public:
    SUBTHREAD(const SOCKET client, const int ID, MAINTHREAD *Server);

    void handleQFStreaming(const vector<string> &splitMessage);
    void handleIncoming(const string &message, const int &length);
    void run();

private:
    MAINTHREAD *Server;
    SOCKET client;
    vector<thread> QFSThreads;
    int ID;

};

void SUBTHREAD::handleQFStreaming(const vector<string> &splitMessage) {
     ...
}

void SUBTHREAD::handleIncoming(const string &message, const int &length) {
     ...
     QFSThreads.push_back(thread(&SUBTHREAD::handleQFStreaming, this, splitMessage));
     ...
}

编辑：我得到的整个错误是：

Answer 1

问题是

vector<thread> QFSThreads;

不允许复制std :: thread。

@see http://www.cplusplus.com/reference/thread/thread/thread/

C ++ std :: thread在当前类
