在ASIO里,就是udp::socket的send_to和receive_from方法(异步版本是async_send_to和asnync_receive_from)。 下面的示例代码是从ASIO官方文档里拿来的(实在想不出更好的例子了:-P): 服务器端代码 // // server.cpp // ~~~ // // Copyright (c) 2003-2008 Christopher M. Kohlhoff // (chris at kohlh...

receive_from和async_send_to函数。总的来说，asio简化了网络编程的繁琐步骤，通过io_context和buffer等核心工具，提供了一套高效、可扩展的网络编程框架。无论是TCP还是UDP，asio都能支持同步和异步操作，极大地提高了开发效率。对网络编程有需求的C/C++开发者，asio是值得深入学习和使用的工具。
