Windows下使用C语言的周期多路UDP编程发送和接收网络调试助手数据

代码：

#include <Windows.h>                //需要包含该头文件
#include <stdio.h>
 
#pragma comment(lib,"Winmm.lib")	//For timeSetEvent

#include <WinSock2.h>
#pragma comment(lib, "ws2_32.lib")  //加载 ws2_32.dll

unsigned short  thisPort[8] = {1234,1235,1236,1237,1238,1239,1240,1241};
unsigned short  otherPort[8] = {1242,1243,1244,1245,1246,1247,1248,1249};

    //创建套接字
    SOCKET sock = socket(PF_INET, SOCK_DGRAM, 0);

//定时器1的回调函数
void WINAPI TimerCallback1(UINT uTimerID, UINT uMsg, DWORD_PTR dwUser, DWORD_PTR dw1, DWORD_PTR dw2)

//定时器2的回调函数

}

    // 设置定时器
	int timerID1 = timeSetEvent(1000, 1, (LPTIMECALLBACK)TimerCallback1, dwUser, TIME_PERIODIC);    
	if(timerID1 != NULL)

	timeKillEvent(timerID1);    //关闭定时器1

网络调试助手设置如下：

可以看出代码同时使用两路UDP和网络调试助手双工通信起来了。
