Re: [lwip-users] httpd example - code suggestions needed

[Bahadir Balban]

Thank you Michael,

Your code works better than the initial one. The only significant difference 
is deleting the netbuf after reading the data into rq:

        netbuf_data(inbuf, (void **)&rq, &len);
        netbuf_delete(inbuf);

Which, in fact clarified and solved the buffer problem.

Strangely, now the code works for exactly 4 connections but no more.
I went through the code with gdb and after the 4th request it is stuck in the 
line:

        if(inbuf = netconn_recv(conn) == NULL )

It never comes out of this function call, while the browser still attempts to 
connect. I know it isn't easy to guess the reasons since these are high level 
functions, but does anybody have any idea of what the cause could be? If 
there's a fatal mistake it shouldn't work until the 5th connection. A buffer 
is overflown maybe after the 4th conn? 

(Just to note: I am running lwip along eCos, on an ARM7TDMI platform)

Cheers,
Bahadir
