udp_input() function

Process an incoming UDP datagram. Given an incoming UDP datagram (as a chain of pbufs) this function finds a corresponding UDP PCB and hands over the pbuf to the pcbs recv function. If no pcb is found or the datagram is incorrect, the pbuf is freed.

Syntax

void udp_input (struct pbuf *p,     struct netif *inp);
Implemented in udp.c:193

Arguments

p

pbuf to be demultiplexed to a UDP PCB (p->payload pointing to the UDP header)

inp

network interface on which the datagram was received.
