[lwip-users] [lwip] threads, semaphores and raw interface question

[leon . woestenberg]

Hello Adam,

in your RFC for v0.5's sys_arch you mention that threads do not
have to be supported in the underlying (OS) layer.

However, there are semaphore signal and wait actions in the code,
so I would conclude that the lwIP code assumes the presence of
more than 1 thread.

In our current standalone application, how would we include the
lwIP TCP/IP stack? Do we need to use the (new?) callback,
and do we have to make the semaphore calls empty?

BTW, I've finished porting my cs8900a driver to lwIP. I'm now
at the point of starting to test it. That actually brought me to the
questions above.

Best Regards,

Leon Woestenberg
