Hi All:
      when i use  "getaddrinfo(NULL, port, &hints, &res))" when 
 "(bind(*sock, res->ai_addr, res->ai_addrlen)",I find the port isn't opened.
I find in the lwip_getaddrinfo's code as follow:

if (nodename != NULL) {
    /* service location specified, try to resolve */
    err = netconn_gethostbyname(nodename, &addr);
    if (err != ERR_OK) {
      return EAI_FAIL;
  } else {
    /* service location specified, use loopback address */
    addr.addr = INADDR_LOOPBACK;

the address is loopback'address "",but i don't enable the loopback
,can I change it to "IP_ADDR_ANY"?
