客户端程序： #include <Winsock2.h>
#include <stdio.h> void main()
{
//加载套接字库
WORD wVersionRequested;
WSADATA wsaData;
int err; wVersionRequested = MAKEWORD (1,1); err = WSAStartup (wVersionRequested, &wsaData);
if (err != 0)
{
  return;
} if (LOBYTE(wsaData.wVersion)!=1||
  HIBYTE(wsaData.wVersion)!=1)
{
  WSACleanup();
  return;
} //创建套接字
SOCKET sockClient = socket (AF_INET,SOCK_STREAM,0); SOCKADDR_IN addrSrv;
addrSrv.sin_addr.S_un.S_addr = inet_addr("192.168.1.2");
addrSrv.sin_family = AF_INET;
addrSrv.sin_port = htons (6000);
//向服务器发出连接请求
connect(sockClient,(SOCKADDR*)&addrSrv,sizeof(SOCKADDR)); //接收数据
char data='0';
int time=120;
do {
   recv(sockClient,&data,sizeof(char),0);
   //发送数据
   if(data=='1')
   {
    printf("data=%c ",data);
    data='0';
    send(sockClient,&data,sizeof(char),0);
   }
   printf("data=%c ",data);
   Sleep(1000);
} while(time);
closesocket(sockClient);
WSACleanup();
}
服务器端程序： #include <Winsock2.h>
#include <stdio.h> void main()

{
  return;
} if( LOBYTE(wsaData.wVersion)!=1||
  HIBYTE(wsaData.wVersion)!=1)
{
  WSACleanup();
  return;
} //创建用于监听的套接字
SOCKET sockSrv = socket (AF_INET,SOCK_STREAM,0); SOCKADDR_IN addrSrv;
addrSrv.sin_addr.S_un.S_addr = htonl (INADDR_ANY);
addrSrv.sin_family = AF_INET;
addrSrv.sin_port = htons(6000); //绑定套接字
bind(sockSrv,(SOCKADDR*)&addrSrv,sizeof(SOCKADDR));
//将套接字设为监听模式，准备接受客户请求
listen(sockSrv,5); SOCKADDR_IN addrClient;
int len = sizeof(SOCKADDR);
char data='1';
  SOCKET sockConn = accept(sockSrv,(SOCKADDR*)&addrClient,&len);
  while(1)
  {
  //发送数据
   send(sockConn,&data,sizeof(char),0);
  //接收数据
   recv(sockConn,&data,sizeof(char),0);
   if(data=='0')

    data='1';
   }
  }

// }
