Hi,
I'm attempting to integrate lwIP into an embedded application
framework that supplies its own poll like functionality. I would like
to make it so that lwIP sockets can be added to the framework's
implementation of poll rather than having a dedicated lwIP thread.
I'd be interested in hearing i

I don't think the same port will run on a preemptive and a
non-preemptive OS, even if it is the same OS.
Did you check your port ? It will surely rely on some semaphores/mutexes
for proper operation; I don't know how they will behave on a cooperative
scenario.
Anyway, your port provider should know

Hi,
We are using lwip on our project. Lwip is use as a client for audio

Hi John,
When I was trying out lwip, the win32 port was the first thing I got
working. It's useful when you want to evaluate lwip and see how best
to integrate it into your application. I imagine, that's the primary
purpose of this port and that's how most people would use it.

I'm implementing a very minimal HTTP proxy server, using lwIP (1.3.1)

I've based my code on the sample http webserver that is provided along

The way the server works is simple. Eg: A request like http:///local/index.htm
Hi michael,
First you need a port to use lwIP o your platform. There are existing
ports for unix and win32 in the conrtib module.
As to your application: I guess you would need to write a virtual

src/netif/ethernetif.c and use this
