Typedef Documentation

typedef u8_t(* raw_recv_fn)(void *arg, struct raw_pcb *pcb, struct pbuf *p, const ip_addr_t *addr)

Function prototype for raw pcb receive callback functions.

Parameters:

arg	user supplied argument (raw_pcb.recv_arg)
pcb	the raw_pcb which received data
p	the packet buffer that was received
addr	the remote IP address from which the packet was received

Returns:: 1 if the packet was 'eaten' (aka. deleted), 0 if the packet lives on If returning 1, the callback is responsible for freeing the pbuf if it's not used any more.
