IBDA_IPV4Filter::GetMulticastListSize

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

Syntax

  HRESULT GetMulticastListSize(
  ULONG*  pulcbAddresses
);

Parameters

  pulcbAddresses

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

Return Values

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.

Requirements

Header: Include bdaiface.h.
