[lwip-users] Send a DNS request

[toto.conseil]

Hi,

I use EVK1100 with AVR studio 2.6.
I need to send DNS request on the server for to connect my card. I work with 
TCP 
protocol. 

I want to use netconn_gethostbyname function. It's a good way ? The problem is 
that the 
function returns ERR_VAL (-8 or Illegal value) and I don't know why. Here is my 
code :


char name[19];

err_t err;

struct ip_addr AddrFree;

sprintf(name,"www.google.fr");

dns_init();

err=netconn_gethostbyname(name, &AddrFree);


There are dns_getserver or dns_send or other which can maybe help me?
Somebody has a idea ?
Thanks in advance.

Emmanuel.
