Function Documentation

netifapi_arp_add()

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.

Parameters

ipaddr	IPv4 address of cache entry
ethaddr	hardware address mapped to ipaddr
type	type of ARP cache entry

Returns

ERR_OK: entry added/updated, else error from err_t

netifapi_arp_remove()

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

Parameters

ipaddr	IPv4 address of cache entry
type	type of ARP cache entry

Returns

ERR_OK: entry removed, else error from err_t

netifapi_netif_common()

err_t netifapi_netif_common	(	struct netif *	netif,
		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.

Note

use only for functions where there is only "netif" parameter.
