View the official Windows Driver Kit DDI referenceNo description available.
The DxgkDdiCloseAllocation function unbinds device-specific allocations that the DxgkDdiOpenAllocation function created.
hDevice [in]A handle to the graphics context device that allocations are unbound from. The display miniport driver's DxgkDdiCreateDevice function previously provided this handle to the Microsoft DirectX graphics kernel subsystem in the hDevice member of the DXGKARG_CREATEDEVICE structure.
pCloseAllocation [in]A pointer to a DXGKARG_CLOSEALLOCATION structure that contains information about unbinding allocations.
DxgkDdiCloseAllocation returns STATUS_SUCCESS, or an appropriate error result if the allocations are not successfully unbound from the graphics context device.
Before the display miniport driver receives a call to its DxgkDdiDestroyAllocation function to release allocations, the driver calls the DxgkDdiCloseAllocation function to close all bindings to those allocations.
For a resource that contains multiple allocations, the DirectX graphics kernel subsystem directs DxgkDdiCloseAllocation to simultaneously close all of the allocations by specifying the handles to the device-specific allocations in the pOpenHandleList member of the DXGKARG_CLOSEALLOCATION structure.
DxgkDdiCloseAllocation should be made pageable.
