D3DDDICB_DEALLOCATE structure (d3dumddi.h)

The D3DDDICB_DEALLOCATE structure describes allocations to release.

Syntax

typedef struct _D3DDDICB_DEALLOCATE {
  [in] HANDLE              hResource;
  [in] UINT                NumAllocations;
  [in] const D3DKMT_HANDLE *HandleList;
} D3DDDICB_DEALLOCATE;

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 Microsoft 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.
