* imexChannel [IN]

*
* packet [IN/OUT]
* Bag of bits which uniquely identifies this object universally.
* - When a new object is allocated, "packet" is returned as output.
* - If NV_MEM_EXPORT_FLAGS_DUP_BY_UUID is provided, "packet" is used as

* numMaxHandles [IN/OUT]
* Max number of memory handles to be attached to the export object.
* - Input when a new object is allocated.
* - Output When duplicating.

* flags [IN/OUT]
* One of NV_MEM_EXPORT_FLAGS_*
* - Input when a new object is allocated or duplicated.
* - Output when duplicating. The flags at the time of allocation are
* returned.
*
* metadata [IN/OUT]
* Private data about the export object (opaque to kernel mode)
* - Input when a new object is allocated.
* - Output When duplicating.
*
* deviceInstanceMask [OUT]
* Attached device instance mask
*
* giIdMasks [OUT]
* Attached GPU instance ID mask (MIG is currently not supported)
* Must be indexed using deviceInstanceMask.
*
* numCurHandles [OUT]
* Number of memory handles currently attached to the export object.
