RE : [lwip-users] Weird behavior of lwIP with C functions

[Louis Filasky]

Hi Frederic,

Thank you for your quick reply,

Well, I was wondering about the netbuf_copy_partial function you talked to me about. Isnt it a socket api function? I am using the raw api and well, I can see what you mean when you say that there is a chain of pbuf when data is received and I am only taking the data of the first current pbuf received. You re right saying it could be handled better, still the command line I am sending to Virtex II are no more longer than 10 chars so I guess it shouldn't cause the software to crash. Besides I debugged the code by removing some
parts and see how the server behaves. No problem appears to come before i check the commandType variable with a strncpy, then in this if, it starts behaving weirdly.

Anyway, regarding sprintf, is memcpy better?

Thanks again,

Antoine.
