IMcastLeaseInfo::get_Addresses method (mdhcp.h)

[Rendezvous IP Telephony Conferencing controls and interfaces are not available for use in Windows Vista, Windows Server 2008, and subsequent versions of the operating system. The RTC Client API provides similar functionality.]

The get_Addresses method obtains the collection of multicast addresses that are the subject of this lease or lease request. This method is primarily for Visual Basic and other scripting languages; C++ programmers use EnumerateAddresses instead.

Syntax

HRESULT get_Addresses(
  [out] VARIANT *pVariant
);

Parameters

[out] pVariant

Pointer to a VARIANT receiving an ITCollection of BSTR strings. Each string is an IP version 4 address in dotted quad notation (for example, 10.111.222.111).

Return value

This method can return one of these values.

Value	Meaning
S_OK	Method succeeded.
E_POINTER	The caller passed in an invalid pointer argument.
E_OUTOFMEMORY	Not enough memory to allocate the collection.

Remarks

Each address is an IP version 4 address represented as a BSTR in dotted quad notation (for example, 10.111.222.111).

TAPI calls the AddRef method on the ITAddress interface returned by IMcastLeaseInfo::get_Addresses. The application must call Release on the ITAddress interface to free resources associated with it.

This function may send data over the wire in unencrypted form; therefore, someone eavesdropping on the network may be able to read the data. The security risk of sending the data in clear text should be considered before using this method.
