Use a reference object
After a reference object has been created (either explicitly by calling CreateRtReferenceObject or implicitly by looking up an object on a remote node) it can be used in any INtime call that accepts the type of the original object.
GetRtObjectInfo fills an OBJECT_INFO structure with details on the referenced object.
When a reference object refers to a memory object, mapping it into the current process memory space can only succeed when the remote node and the local node are on the same host (PC).
If the remote node might be on a different host, with a different deployment, you should not map the memory but instead should use CopyRtData.
