client.cpp

这是eenet的具体实现方案的客户端！用于模拟计算机终端！

#include <stdio.h>
#include <conio.h>
#include <string.h>
#include "mytypes.h"
#include "mysock.h"

int Client(SOCKET s, int port, u_long addr);
int main(int argc,char *argv[])
{
	SOCKET s;
	int id;
	if(argc == 1)
	{
		printf("Usege %s ID\n",argv[0]);
		return 0;
	}
	sscanf(argv[1],"%d",&id);
	if(id < 0 || id > 9)
	{
		printf("%s out of range [1..9]\n",argv[1]);
		return 0;
	}
	s = OpenSocket(IPPROTO_UDP);
	if(s == INVALID_SOCKET)
		SockErrMsg();
	Client(s,3000+id,0x7f000001);
	
	return 0;
}

int Client(SOCKET s, int port, u_long addr)
{
	SockAddr Dst;
	SockAddr Src;
	char str[]="hello,this is the first message.\n";
	char buff[80];
	
	Dst.port = port;
	Dst.addr = addr;
	SendTo(s, str,strlen(str)+1,&Dst);
	if (RecvFrom(s,buff,80,&Src,1000))
	{
		printf("data received.\n%s\n",buff);
	}
	return 0;
