Function Documentation

int MLDJoinGroup	(	NETIF_DEVICE *	ptr_device,
		IP6N	multicast_address
	)

Description
This function is used to join a multicast group over a specific interface.

This is for *internal* NDK Stack Usage.

Parameters:

[in]	ptr_device	The pointer to the NIMU Network Interface object over which the multicast address is being joined.
[in]	multicast_address	IPv6 Multicast address being joined.

Return values:

	0	- Success
	<0	- Error

int MLDLeaveGroup	(	NETIF_DEVICE *	ptr_device,
		IP6N	multicast_address
	)

Description
This function is used to leave a multicast group over a specific interface.

This is for *internal* NDK Stack Usage.

Parameters:

[in]	ptr_device	The pointer to the NIMU Network Interface object over which the multicast address is being left.
[in]	multicast_address	IPv6 Multicast address being left.

Return values:

	0	- Success
	<0	- Error

int MLDTestGroup	(	NETIF_DEVICE *	ptr_device,
		IP6N	multicast_address
	)

Description
This function is called from the IPv6 Stack receive handler to verify if the address specified here has been joined or not?

This is for *internal* NDK Stack Usage.

Parameters:

[in]	ptr_device	Pointer to the Network Interface object on which the IPv6 packet was rxed.
[in]	multicast_address	This is the IPAddress from the Destination field of the IPv6 Packet.

Return values:

	1	- Multicast Group has been joined
	0	- The group has not been joined.
