lwIP has a number of different APIs.  The most familiar will be the
sockets API, but I'm not sure if this supports all the non-blocking
features you might need.  It is certainly able to do non-blocking reads
however.

Alternatively, you could use the "raw" API, which is callback based, so
should fit your needs, but may be less intuitive.  Unfortunately the
homepage that has some documentation about this
(http://www.sics.se/~adam/lwip) seems to be unreachable at the moment.

Hope that helps,
