7.2. I/O 服务与 I/O 对象 7.2. I/O 服务与 I/O 对象 使用 Boost.Asio 进行异步数据处理的应用程序基于两个概念：I/O 服务和 I/O 对象。 I/O 服务抽象了操作系统的接口，允许第一时间进行异步数据处理，而 I/O 对象则用于初始化特定的操作。 鉴于 Boost.Asio 只提供了一个名为 boost::asi...

15.2. Boost.System 15.2. Boost.System Boost.System 是一个定义了四个类的小型库，用以识别错误。 boost::system::error_code 是一个最基本的类，用于代表某个特定操作系统的异常。 由于操作系统通常枚举异常，boost::system::error_code 中以变量的形式保存...
