| err_t netifapi_arp_add | ( | const ip4_addr_t * | ipaddr, | 
| struct eth_addr * | ethaddr, | ||
| enum netifapi_arp_entry | type | ||
| ) | 
Add or update an entry in the ARP cache. For an update, ipaddr is used to find the cache entry.
| ipaddr | IPv4 address of cache entry | 
| ethaddr | hardware address mapped to ipaddr | 
| type | type of ARP cache entry | 
| err_t netifapi_arp_remove | ( | const ip4_addr_t * | ipaddr, | 
| enum netifapi_arp_entry | type | ||
| ) | 
Remove an entry in the ARP cache identified by ipaddr
| ipaddr | IPv4 address of cache entry | 
| type | type of ARP cache entry |

| netifapi_void_fn | voidfunc, | ||
| netifapi_errt_fn | errtfunc | ||
| ) | 
call the "errtfunc" (or the "voidfunc" if "errtfunc" is NULL) in a thread-safe way by running that function inside the tcpip_thread context.
