Hi Nenad,
Did you check errno?

Subject: [lwip-users] lwip_select never returns value > 0
Hi people,
I am trying to use lwip_select in combination with lwip_recv. I have
done it like this so far:
FD_ZERO(&rfds);
FD_SET(new_sd, &rfds);
tv.tv_sec = 0;
tv.tv_usec = 200000;
if (lwip_select(new_sd + 1, &rfds, NULL, NULL, &tv) > 0)
{
lwip_recv()
}
No matter what, timeout always exceeds. Am I doing anything wrong?
Should I include some lwip option in order to use lwip_select()?
I am using lwip v1.4.1.
Regards,
Nenad
