(一)thread类摘要及分析 classthread {//class for observing and managing threadspublic:classid;usingnative_handle_type =void*; thread() noexcept : _Thr{} {//创建空的thread对象,实际上线程并未被创建!}private: template<class_Tu
template<classFn,class... Args>explicitthread(Fn&& fn,Args&& ... args); &&表示既可以传入左值也可以传入右值。 (3)拷贝构造函数。 代码语言:C++ 代码运行次数:0 自动换行 运行 AI代码解释 // 如果拷贝构造函数(被禁用),意味着 thread 不可被拷贝构造。thread(constthread&) =delete; (4)move构造函数 ...
既然已引入RAII思想，我们自然可以借助该思想来解决因忘记join或detach而导致的崩溃问题。因此，std::jthread应运而生。值得一提的是，std::jthread并非仅限于此。为深入理解std::jthread的运作机理，剖析其源码是个不错的选择。以下是std::jthread的部分源码整理：if _HAS_CXXclass jthread {public: jthread() ...
class thread_guard { private: std::thread& t; public: // 构造函数,接收线程引用 explicit thread_guard(std::thread& t_) : t(t_) {} // 析构函数,自动join线程 ~thread_guard() { if (t.joinable()) { t.join(); } } // 禁止复制 thread_guard(const thread_guard&) = delete; thread...
