IEnumMcastScope::Clone 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 Clone method creates another enumerator that contains the same enumeration state as the current one.
HRESULT Clone( [out] IEnumMcastScope **ppEnum );
Pointer to the new IEnumMcastScope object.
This method can return one of these values.
||The ppEnum parameter is not a valid pointer.|
||Insufficient memory exists to perform the operation.|
||Failed for unknown reasons.|
TAPI calls the AddRef method on the IEnumMcastScope interface returned by IEnumMcastScope::Clone. The application must call Release on the IEnumMcastScope interface to free resources associated with it.
