IWbemClassObject::Clone method

The IWbemClassObject::Clone method returns a new object that is a complete clone of the current object. The new object has a COM reference count of 1.

Syntax

HRESULT Clone(
  [out]  IWbemClassObject **ppCopy
);

Parameters

ppCopy [out]

This parameter cannot be NULL. It receives the copy of the current object. You must call IWbemClassObject::Release on this object when it is no longer required.

A new object is not returned on error.

Return value

This method returns an HRESULT indicating the status of the method call. The following table lists the value contained within an HRESULT.

Remarks

Use this method to duplicate a class definition, or to duplicate an instance. This can be useful when the original copy of the object is required for backup purposes while a new copy is modified. Likewise, use this method to create many new instances from a single source instance. For example, use IWbemClassObject::SpawnInstance to create a single starting instance, and use IWbemClassObject::Clone to produce 100 copies of the instance quickly. Each object can be modified subsequently to take on its particular values.

It is not possible to use this method to convert a class definition into an instance, or convert an instance into a class definition.
