Creates a deep copy of this ICondition object.
HRESULT Clone( ICondition **ppc );
[out, retval] Receives a pointer to the clone of this ICondition.
Returns S_OK if successful, or an error value otherwise.
Because there are no methods for modifying an ICondition, there are few occasions when this method is necessary. In many cases it is adequate to call the IUnknown::QueryInterface method on the ICondition to obtain an additional reference to the same object.
