IBDA_IPV4Filter::GetMulticastListSize Method

The GetMulticastListSize method retrieves the number of addresses in the list.

Syntax

HRESULT GetMulticastListSize(
  [in, out]  ULONG *pulcbAddresses
);

Parameters

• pulcbAddresses [in, out]
  Pointer that receives the number of addresses multiplied by the size of an IPv4 address.

Return Value

If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

This method is used by an IPv4 Network Data Sink filter to request that a Network Provider make its best effort to tune to the stream(s) on which a list of IPv4 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 IPv4 address.
