  PLUID   DeviceLuid,
  UINT64  Length,
  BYTE [] RestoreBuffer
);

Parameters

DeviceLuid

[in] Pointer to a LUID structure that represents the locally unique identifier (LUID) of the device whose immutable state is to be restored.

Length

[in] Pointer to a variable that specifies the length in bytes of the buffer that RestoreBuffer points to.

RestoreBuffer

[in] Pointer to a buffer that contains the immutable state of the vGPU that was previously stored.

Return value

RestoreImmutableGpup returns an HRESULT value that indicates the status of the method call. Possible return values include, but are not limited to, the following:

Return value	Description
S_OK	The method call was successful.
E_INVALIDARG	The buffer is not large enough to store the immutable state.
