RE: [lwip-users] udp_send: space for IP header is not being allocated?

[Grubb, Jared]

You might check out the "tasks" list on the source website. We're currently 
working on documenting things, and both of what you mention is in the works.

I created a receive flow diagram for a TCP packet. You should check it out, 
it's called RX_FLOW.PDF. It can be a good help trying to troubleshoot what is 
going on when things fail.

After some thinking, here is what I believe might help me the most:

- Code templates for most of the possible lwIP configurations (e.g.
UDP versus TCP, listening versus connecting, RAW API versus POSIX API,
interrupts versus polling, ...).  These don't even have to be full
source code examples - they can just be lwIP functions interspersed
with pseudocode.

- Perhaps some picture/graphic which shows the flow of data through
functions in the lwIP stack
