The GetMulticastListSize method retrieves the size in bytes of the list of multicast addresses.
Syntax
HRESULT GetMulticastListSize(
ULONG* pulcbAddresses
);
Parameters
pulcbAddresses
[in, out] Pointer that receives the size in bytes.
Return Values
If the method succeeds, it returns S_OK. If it fails, it returns an error code.
Remarks
This method is used by the BDA IP Sink filter to request that a Network Provider make its best effort to tune to the stream(s) on which a list of IPv6 multicast addresses may be transmitted. Addresses in the address list are byte aligned in Network order. UlcbAddresses will always be an integer multiple of the size of an IPv6 address.
