今天给大家介绍asio多线程模式的第二种,之前我们介绍了IOServicePool的方式,一个IOServicePool开启n个线程和n个iocontext,每个线程内独立运行iocontext, 各个iocontext监听各自绑定的socket是否就绪,如果就绪就在各自线程里触发回调函数。为避免线程安全问题,我们将网络数据封装为逻辑包投递给逻辑系统,逻辑系统有一个单独线...
使用Boost库中的boost::asio::thread_pool类(从Boost 1.66.0版本开始提供)或第三方库如boost::threadpool来创建线程池。使用线程池: 将任务提交到线程池,线程池会自动分配线程来执行任务。 等待任务完成并获取结果(如果有的话)。4. C++ Boost线程池的示例代码 以下是使用boost::asio::thread_pool创建和使用线程...
