| ) |
Send an icmp 'destination unreachable' packet, called from ip_input() if the transport layer protocol is unknown and from udp_input() if the local port is not bound.
- Parameters:
-
p the input packet for which the 'unreachable' should be sent, p->payload pointing to the IP header t type of the 'unreachable' packet
Definition at line 301 of file lwip_icmp.c.
Processes ICMP input packets, called from ip_input().
Currently only processes icmp echo requests and sends out the echo response.
- Parameters:
-
p the icmp echo request packet, p->payload pointing to the icmp header inp the netif on which this packet was received
Definition at line 80 of file lwip_icmp.c.
| void icmp_time_exceeded | ( | struct pbuf * | p, |
| enum icmp_te_type | t | ||
| ) |
Send a 'time exceeded' packet, called from ip_forward() if TTL is 0.
- Parameters:
-
p the input packet for which the 'time exceeded' should be sent, p->payload pointing to the IP header t type of the 'time exceeded' packet
Definition at line 316 of file lwip_icmp.c.
