Parameters

`hDevice`

A handle to the display device associated with the allocation

`unnamedParam2`

A pointer to a D3DDDI_UPDATEALLOCPROPERTY structure that describes how to update the allocation with the desired properties.

Return value

pfnUpdateAllocationPropertyCb returns one of the following values:

Return code	Description
STATUS_SUCCESS	The properties were successfully updated. The driver can start using the allocation with its new property immediately. PagingFenceValue is invalid, though the driver shouldn't wait on it.
STATUS_PENDING	The request has successfully been queued to VidMm and is being processed. The driver must synchronize against the returned PagingFenceValue before using the allocation with its new property. Note that if the driver request is invalid it may still fail at a later point, in which case the device will be put in error.
E_INVALIDARG	Invalid call with bad arguments provided.
E_OUTOFMEMORY	Desired supported memory segment is full.
E_FAIL	An unknown error has occurred.
