看一个开源项目，示例代码是最直接的教程了。

ACE的Reactor代码如下图所示：

 打开README

This directory contains subdirectories that test the ACE Reactor and Proactor

  . Dgram
    Tests the CODgram and Dgram classes with the Reactor.

  . Misc
    Various miscellaneous tests of Reactor functionality
    (e.g., signals, timers, notification, etc.).

  . Multicast
    Tests out the ACE multicast capabilities in conjunction
    with the Reactor.

  . Ntalker
    A program that implements a multicast "chat" program.


  . Proactor
    A program that illustrates the "Proactive" version of
    the Reactor

用表格展示

代码	内容
Dgram	基于UDP协议，包括ACE_SOCK_Dgram和ACE_SOCK_CODgram http://www.dre.vanderbilt.edu/Doxygen/5.4/html/ace/a01650.html http://www.dre.vanderbilt.edu/Doxygen/5.4/html/ace/a01647.html
FIFO	FIFO一般指先入先出队列。用FIFO实现的服务——客户模型是用一个公共的只读管道接受请求，然后根据请求进程的进程ID另创建一个新的管道与其通信。
Misc	Reactor所有函数的测试例子
Multicast	UDP广播 https://blog.csdn.net/qq_41278986/article/details/118311200
Ntalker	This test program illustrates how the ACE datagram multicast feature works.
Proactor	This README file lists all the example applications for the Proactor framework.在高性能的I/O设计中，有两个比较著名的模式Reactor和Proactor模式，其中Reactor模式用于同步I/O，而Proactor运用于异步I/O操作。 https://blog.csdn.net/weiwangchao_/article/details/42917507
TP_Reactor	This program demonstrates what we think is a bug in the ACE library. The affected component is the ACE_TP_Reactor. According to the documentation, the reactor ensures that only one of the handle_*() methods of an event handler is called at a time. Tino found this to be not true and I wrote this example program showing the behavior. I do not exclude the possibility that we are using the ACE library in an unintended/wrong way. So comments on the code as well as any other remarks are welcome. 就是ACE的Reactor测试框架 https://blog.csdn.net/chinaclock/article/details/49120497 https://blog.csdn.net/bingozq/article/details/2453570
WFMO_Reactor	WFMO_Reactor是ACE_Reactor在Windows下的默认实现（为什么不选择ACE_Select_Reactor作为默认实现，可能是基于效率和强大性的考虑）,WFMO_Reactor的低层使用的函数是WaitForMultipleObjects和WSAEventSelect，WSAEnumNetworkEvents。其中WaitForMultipleObjects函数用于处理线程，互斥量，信号灯，事件，定时器等事件，而WSAEventSelect用于处理网络IO事件。 https://blog.csdn.net/fullsail/article/details/2901792

总结：

Reactor的应用程序继承ACE_Event_Handler类，调用相关的封装实现网络通讯，包括UDP和TCP协议。自带断线重连功能。非常好用。
