Re: [lwip-users] a beginners questions about lwip, sockets and threads

Thanks,

the reasons for upgrading were pretty
convincing and the upgrade was pretty smooth I must say. Even if the documentation
don't seem to be quite up to date. I'll see if I can find time to update
the wiki tonight.

For now I'll try to get a socket example
working in cygwin and then see if I can get the same code to execute under
lwip.

You can, but I would do it all in one thread, and use poll() to
determine when each socket needs attention (either sending or
receiving).

Either.

Not really, no.

Yes: (i) you're likely to get much better support from the developers if
you're using 1.4.0; (ii) lots of bug fixes; (iii) improved performance;
(iv) etc!
