#define netif_mld6_data

(

)

((struct mld_group *)netif_get_client_data(netif, LWIP_NETIF_CLIENT_DATA_INDEX_MLD6))

Get list head of MLD6 groups for netif. Note: The allnodes group IP is NOT in the list, since it must always be received for correct IPv6 operation.

Function Documentation

mld6_joingroup()

err_t mld6_joingroup	(	const ip6_addr_t *	srcaddr,
		const ip6_addr_t *	groupaddr
	)

Join a group on a network interface.

Parameters

srcaddr	ipv6 address of the network interface which should join a new group. If IP6_ADDR_ANY, join on all netifs
groupaddr	the ipv6 address of the group to join

Returns

ERR_OK if group was joined on the netif(s), an err_t otherwise

mld6_joingroup_netif()

err_t mld6_joingroup_netif	(	struct netif *	netif,
		const ip6_addr_t *	groupaddr
	)

Join a group on a network interface.

Parameters

netif	the network interface which should join a new group.
groupaddr	the ipv6 address of the group to join

Returns

ERR_OK if group was joined on the netif, an err_t otherwise

mld6_leavegroup()

err_t mld6_leavegroup	(	const ip6_addr_t *	srcaddr,
		const ip6_addr_t *	groupaddr
	)

Leave a group on a network interface.

Parameters

srcaddr	ipv6 address of the network interface which should leave the group. If IP6_ISANY, leave on all netifs
groupaddr	the ipv6 address of the group to leave

Returns

ERR_OK if group was left on the netif(s), an err_t otherwise

mld6_leavegroup_netif()

err_t mld6_leavegroup_netif	(	struct netif *	netif,
		const ip6_addr_t *	groupaddr
	)

Leave a group on a network interface.

Parameters

netif	the network interface which should leave the group.
groupaddr	the ipv6 address of the group to leave

Returns

ERR_OK if group was left on the netif, an err_t otherwise
