Description
TPtrWrapper is a pointer-sized value representing a pointer.
TPtrWrapper has the same size as a pointer. It is designed so that it can be used where a pointer would appear in an API declaration, avoiding casting back and forth.
This wrapped pointer is used in the process of marshalling, applied by the low-level TMarshal, and the high-level TMarshaller APIs.
