void detach(); (C++11 起) 从thread 对象分离执行线程,允许它独立地持续执行。当该线程退出时将释放其分配的任何资源。 调用detach 后*this 不再占有任何线程。 参数(无) 返回值(无) 后条件joinable 为false。 异常若joinable() == false 或出现任何错误则为 std::system_error。
1,std::thread 禁用了拷贝构造函数(thread(const thread&) = delete),无法被拷贝构造。 2,std::thread 禁用了拷贝赋值重载(thread& operator=(const thread&) = delete),无法被拷贝赋值。 3,std::thread 可以被移动赋值: thread&operator=(thread&&rhs) noexcept; std::thread t3(PrintID); std::thread t4...

默认构造函数,创建一个空的 std::thread 执行对象。 初始化构造函数,创建一个 std::thread 对象,该 std::thread 对象可被 joinable,新产生的线程会调用 fn 函数,该函数的参数由 args 给出。 拷贝构造函数(被禁用),意味着 std::thread 对象不可拷贝构造。 Move 构造函数,move 构造函数(move 语义是 C++11 ...
