7.Initiator 执行特定程序代码启动异步操作,初始化器通过如basic_stream_socket等高层次接口与异步操作处理器交互,并返回reactive_socket_service等类型的服务代理。 六、常用内容 1.asio::io_context asio提供的一个基本的io对象,只有调用其run方法的线程才会被asio调度去执行任务,可以通过post方法添加一个任务。 asio:...

比如正则表达式本身(basic_regex)与一次匹配的结果(match_results)是不可变的;而匹配动作本身(match_regex)涉及状态更新,是可变的,于是用可重入的函数将其封装起来,不让这些数据泄露给别的线程。正是由于做了这样合理的区分,regex 在正常使用时就不必加锁。
boost::asio::ip::tcp::socket& socket() const正在返回类型为boost::asio::ip::tcp::socket的_socket,并给出此错误 error: invalid initialization of non-const reference of type ‘boost::asio::basic_stream_socket<boost::asio::ip::tcp, boost::asio::stream_socket_service<boost::asio::...

As an introductory example, let's consider what happens when you perform a connect operation on a socket. We shall start by examining synchronous operations. Your program will have at least one I/O execution context, such as an boost::asio::io_context object, boost::asio::thread_pool objec...
