Re: Specific DNS server

[Claus Assmann]

On some OS the following code works - I use that for regression
testing when I need fake DNS data:

void
dns_setns(struct in_addr *ns, unsigned int port)
{
        if ((_res.options & RES_INIT) == 0)
                (void) res_init();
        _res.nsaddr_list[0].sin_family = AF_INET;
        _res.nsaddr_list[0].sin_addr = *ns;
        if (port != 0)
                _res.nsaddr_list[0].sin_port = htons(port);
        _res.nscount = 1;
}
