Comments
You typically do not need to call this function. The only situation in which you would need to call this function is if you are performing custom marshalling (that is, writing your own implementation of IMarshal). You must use CoUnmarshalHresult to unmarshal HRESULTs previously marshalled by a call to the CoMarshalHresult function.
