D3DDDICB_DEALLOCATE2 structure (d3dumddi.h)
The D3DDDICB_DEALLOCATE2 structure describes parameters for releasing allocations with pfnDeallocate2Cb
Syntax
typedef struct _D3DDDICB_DEALLOCATE2 {
[in] HANDLE hResource;
[in] UINT NumAllocations;
[in] const D3DKMT_HANDLE *HandleList;
[in] D3DDDICB_DESTROYALLOCATION2FLAGS Flags;
} D3DDDICB_DEALLOCATE2;
Members
[in] hResource
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.
[in] NumAllocations
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.
[in] HandleList
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.
[in] Flags
A D3DDDICB_DESTROYALLOCATION2FLAGS structure that contains additional details about the operation.
