D3DDDICB_DEALLOCATE2 structure

The D3DDDICB_DEALLOCATE2 structure describes parameters for releasing allocations with pfnDeallocate2Cb

Syntax

typedef struct _D3DDDICB_DEALLOCATE2 {
  HANDLE                           hResource;
  UINT                             NumAllocations;
  const D3DKMT_HANDLE              *HandleList;
  D3DDDICB_DESTROYALLOCATION2FLAGS Flags;
} D3DDDICB_DEALLOCATE2;

Members

hResource

[in] A handle to a resource whose associated allocations must be released. If the user-mode display driver uses the array that is specified by HandleList to specify the allocations to release, it sets hResource to NULL.

NumAllocations

[in] The number of allocations in the HandleList array. If the user-mode display driver sets the handle in the hResource member to non-NULL, NumAllocations is ignored by the Direct3D runtime.

HandleList

[in] An array of D3DKMT_HANDLE data types that represent kernel-mode handles to the allocations. The Direct3D runtime's pfnAllocateCb function returns these handles. Therefore, the user-mode display driver uses these handles to release the allocations.

If the user-mode display driver sets the handle in the hResource member to non-NULL, HandleList is ignored by the Direct3D runtime.

Flags

[in] A D3DDDICB_DESTROYALLOCATION2FLAGS structure that contains additional details about the operation.
