ACE实现动态交互-按下Ctrl+C输出一起-ACE_Event_Handler:handle_signal()

ACE实现动态交互----按下Ctrl+C输出一行----ACE_Event_Handler::handle_signal()

#include "ace/Reactor.h"

#include <iostream>

#define SIGINT 2 //按下control + c  （系统已有定义的信号量）

	//同事调用此类的handle_signal方法
	SignalHandler()

	}  
	int handle_signal(int signum, siginfo_t*,ucontext_t*) //处理信号
