2008/1/23, Frédéric BERNON <address@hidden>:For non-blocking, it should be available in 1.2.0. For SO_RCVBUF and SO_RCVTIMEO, you need 1.3.0.====================================

Theoretically, you can do it in a different task, use select() to wait for
multiple sockets when you would be blocked waiting for input anyway and/or
use non-blocking sockets if you were going to be doing a busy poll anyway.
But the more efficient choice is to enable the LWIP_SO_RCVBUF option in
lwipopts.h and use setsockopt() to set it.
