[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.

Syntax

HRESULT Clone(
  [out] IEnumMcastScope **ppEnum
);

Parameters

[out] ppEnum

Pointer to the new IEnumMcastScope object.

E_POINTER
 The ppEnum parameter is not a valid pointer.
E_OUTOFMEMORY
 Insufficient memory exists to perform the operation.
E_UNEXPECTED
