ISO禁止

？即使我：

void aClass::start(){
    void *ptr = this->startService;
    thread serviceth(ptr,this);
}

我收到了一个错误：＆＃34;没有匹配的呼叫功能＆＃34;。

Answer 1

您需要为std::thread提供类似

的函数指针

void aClass::start(){
    thread serviceth(&aClass::startService, this);
}

为了创建一个线程。但是我们遇到了另一个问题。在创建线程之后，函数结束并且线程被销毁。由于线程处于可连接状态（从未调用join()或detach()），线程的析构函数将抛出异常。

您可以使serviceth成为aClass的成员，以便线程可以在类存在时运行。

ISO禁止启动自己的类方法的线程？
