Problems with a c++ code on a linux pc translate into java windows pc

Question

Hello does anyone know how I can use this c++ code in my java program.
This is a c++ code what we use on a linux pc now I have to make the code
for a windows pc with java.
void GetLocalIP(int s,struct sockaddr_in *local)
   struct ifconf cfg;          // info structure to request our IP addr
   struct ifreq  ifs[3];       // part 2 of info structure
   int done=0;
   int x=0,l;
   // Get local ip addr, make information struct
   cfg.ifc_len = sizeof(ifs);
   cfg.ifc_req = ifs;
   // ioctl interface informatoin into the struct we made
   if (ioctl(s, SIOCGIFCONF, (void*)&cfg) == 0)
       l = cfg.ifc_len / sizeof(struct ifreq);
       while (!done && (x<l))
         if (strcmp("eth0",cfg.ifc_req[x].ifr_name)==0)
           memcpy(local,&(cfg.ifc_req[x].ifr_addr),sizeof(struct sockaddr_in));
           done=1;
         x++;
}

How do you want to "make the code for a windows pc with java" ?
Java can use sockets directly, and you can get the Local IP address by this code..

            System.out.println ("Local Host Name : " + local.getHostName() );
            byte[] ip = local.getAddress();
            // Now do a bit of conversion to print the IP address from a byte array
            System.out.print ("Local Host IP   : " );
            int toUnsignedInt;
            for ( int i=0; i<ip.length; i++ )
