[lwip-users] LWIP core thread

[Lee, Botao]

I am a new comer to LWIP, and have a question regarding using it with threads.

 

In pretty much all the examples I found, a thread (say Thread IN) is created to service in-coming packages, either polling or getting notified by the network interface. But I never found this thread/ or another thread servicing out-going packages.

 

Does this mean the application thread (Thread APP)is actually executing all the LWIP output functions?

 

If this is true, it means that there could be 2 threads executing LWIP code at the same time: Thread IN and Thread APP. This doesnot comply with the LWIP document which says only 1 thread is allowed.

 

Really confused. Hopefully I can get some help here.
