DXGKCB_DESTROYCONTEXTALLOCATION callback function

Description

DXGKCB_DESTROYCONTEXTALLOCATION frees a resource that was previously allocated for a GPU or device-specific context.

Parameters

hAdapter [in]

Handle to the graphics adapter for which the allocation was created. The display miniport driver receives the handle from the DeviceHandle member of the DXGKRNL_INTERFACE structure in a call to its DxgkDdiStartDevice function.

hAllocation [in]

Handle that was assigned by the DirectX graphics subsystem (Dxgkrnl) to the context allocation. The display miniport driver receives the handle from the hAllocation member of the DXGKARGCB_CREATECONTEXTALLOCATION structure in a call to the DXGKCB_CREATECONTEXTALLOCATION function.

Return value

DXGKCB_DESTROYCONTEXTALLOCATION returns STATUS_SUCCESS if it succeeds. Otherwise, it returns one of the error codes defined in Ntstatus.h.

Remarks

The display miniport driver calls DXGKCB_CREATECONTEXTALLOCATION to allocate a context resource. After such a call, the driver can call DXGKCB_DESTROYCONTEXTALLOCATION at any time to free the resource.

DXGKCB_XXX functions are implemented by Dxgkrnl. To use this callback function, call DxgkCbDestroyContextAllocation via the DXGKRNL_INTERFACE.
