Re: [lwip-devel] IPv6 related implementation in Udp.c

[Ivan Delamer]

First you must be using the Head version of LwIP from the GIT 
repository, release versions still don't contain the IPv6 code.

If you are using netconn API you can use the macros such as 
netconn_sendto_ip6()

Otherwise, you can just cast your IPv6 address pointer to an IPv4 
address pointer, and make sure that pcb->isipv6 is set. The stack will 
internally recognize the address as IPv6.

You can also use the ip6_to_ipX macros to turn an ip6 address into 
something neutral to pass into the stack.

Cheers
Ivan
