    #include <stdio.h>

    int main(int argc, char* argv[])
       SOCKET sd,newsd;
     unsigned short int port = 8888;
     unsigned long int total;
     int err;
     char *buf;
     struct sockaddr_in6 local;
    // struct addrinfo local6;

    WSADATA wsaData;

    int wsaret=WSAStartup(0x101,&wsaData);

        //WSAStartup returns zero on success.
        //If it fails we exit.
            return 0;

      //  local.sin6_family=AF_INET6; //Address family
       IN6ADDR_ISANY(&local); //Wild card IP address
        local.sin6_port=htons((u_short)8888); //port to use
     sd = socket(AF_INET6,SOCK_STREAM,0);
     if(sd == INVALID_SOCKET)

     if(err != 0)
      printf( "bind return value ==%d\n",err);
            return 0;

            return 0;


       printf("Waiting for data on port %d\n",port);
       int i =0;
       total = 0;
           newsd = accept(sd,NULL,NULL);
          if(newsd < 0)
          perror("Cannot accept connection");
      return 0;

           buf = (char *)malloc (10000);
        err = recv(newsd,buf,10000,0);
        if(err <= 0)
        total += err;
        printf("\n Total recv : %d in %d times \n",total,i);
       if(err < 0)
        perror("cannot recv data");
        printf("Recv %d bytes\n",(int)total);

     //goto again;
        printf("ending \n");
