在main()函数中我们先使用StartThread()开启执行子线程,然后再通过按q键调用StopThread()退出子线程。 但是我们一不小心就连续按了两下q键,导致调用了两次StopThread()方法,这个时候程序出现了crash,并出现了如下报错: 2 问题原因 在上述main函数中,当我们按下了第一次q键的时候,子程序已经调用了join方法,这导致...
C++中的thread对象通常来说表达了执行的线程（thread of execution），这是一个OS或者平台的概念。当thread::join()函数被调用后，调用它的线程会被block，直到线程的执行被完成。基本上，这是一种可以用来知道一个线程已结束的机制。当thread::join()返回时，OS的执行的线程已经完成，C++线程对象可以被...
如果超时了就标记timeout中断上报流程。 按照https://en.cppreference.com/w/cpp/thread/async和https://en.cppreference.com/w/cpp/thread/future/%7Efuture的对标准的描述。 Async invocation If the async flag is set (i.e. (policy & std::launch::async) != 0), thenstd::asynccallsINVOKE(decay-c...
原因是 std::thread 即可以 join() 也可以 detach()，简单快捷直观，思维上没什么多余的东西。
比如，std::thread可以获取到原生的native handle，以此可以用操作系统作更多控制，比如在linux可以要求某...
