RE : [lwip-devel] Question about tcp_pcb.recv callback parameter

[Frédéric BERNON]

Perhaps for future uses, or to have a prototype like this others callbacks ? (but I don't have check that)...

Objet : [lwip-devel] Question about tcp_pcb.recv callback parameter

The recv callback in tcp_pcb (that is called if LWIP_CALLBACK_API=1) has an argument err. Now it seems that this callback is only called (through the define TCP_EVENT_RECV) from tcp_input(). And from there, always with err = ERR_OK!

What is this argument for then, if it's always ERR_OK??? Couldn't we remove it? Does anyone know more about that?
