That document is a bit outdated. select() is supported.

Hello there,
I try to use a SOCK_DGRAM socket in a non-blocking mode. I would like to have a
code like this :
While(True)
if (sendto( socket, ....)>=0)
{ if (recvfrom( socket...)>=0)
{ do job
}
}
My problem is that the recvfrom is block the process. So, if the peer never answer (or if
the packet is lost), the recvfrom never returns and my process is dead. I have try
SO_RCVTIMEO option, but it seems it is not support by lwIP. I read in the lwIP.pdf
document (Adam Dunkels, Feb 20, 2001, chapiter 17) that "select" is not
supported.
So, How can I do to do a code like this, with a timeout on recvfrom ?
Note I use a lwIP 1.1.0 on a multithread OS. Perhaps a bug in our sys_arch ?
Thanks
