[lwip-users] lwIP and threads

[Thomas Riedrich]

Hello,

I need some clarification on lwIP and threads. The wiki says that lwIP CAN use threads, but doesn’t need threads. What I want to do is the following:

 

Receive pictures using lwIP, store them in a RAM file system, process them, and send them back using lwIP. So I need lwIP to run in ONE thread ALONGSIDE another thread which does the image processing, but I don’t need for lwIP to split up into several threads.

 

So my question is how I would implement sys_arch.c. Would I still have to port it to the multithreading system I’m using? Does lwIP have to “know” that I’m using threads in this case? Or could I just rewrite tcpip_init to use my own start_new_thread function instead of lwIPs own sys_thread_new?

 

Thanks

Tom
