一、线程std::thread简介 std::thread是 C++11 中引入的一个库,用于实现多线程编程。它允许程序创建和管理线程,从而实现并发执行。std::thread在#include<thread>头文件中声明,因此使用std::thread时需要包含#include<thread>头文件。 二、语法 2.1、构造函数 (1)默认构造函数:创建一个空
标记使用std::thread的代码: Suggest use of gsl::joining_thread or C++20 std::jthread. 建议使用gsl::joining_thread或者C++20引入的std::jthread. Suggest "exporting ownership" to an enclosing scope if it detaches. 如果需要分离线程,建议“输出所有权”到封闭的作用域。 Warn if it is not obvious w...
