D3DKMT_RECLAIMALLOCATIONS structure (d3dkmthk.h)

Describes video memory resources that are to be reclaimed and that the driver previously offered for reuse. Used with the D3DKMTReclaimAllocations function.

Syntax

typedef struct _D3DKMT_RECLAIMALLOCATIONS {
  [in]  D3DKMT_HANDLE       hDevice;
  [in]  D3DKMT_HANDLE       *pResources;
  [in]  const D3DKMT_HANDLE *HandleList;
  [out] BOOL                *pDiscarded;
  [in]  UINT                NumAllocations;
} D3DKMT_RECLAIMALLOCATIONS;

Members

[in] hDevice

A D3DKMT_HANDLE data type that represents a handle to the device that created the allocations.

[in] pResources

An array of D3DKMT_HANDLE data types that represent Direct3D runtime resource handles.

[in] HandleList

An array of D3DKMT_HANDLE data types that represent kernel-mode handles to the allocations that are to be reclaimed.

If HandleList is not NULL, the pResources member must be NULL.

[out] pDiscarded

An array of Boolean values that specify whether each resource or allocation was discarded.

Each Boolean value in this array corresponds to a resource at the same index location in the arrays pointed to by pResources or HandleList.

The DirectX graphics kernel subsystem sets each Boolean value to TRUE if the corresponding resource was discarded, or to FALSE if not.

The value of pDiscarded can be NULL. If the driver sets it to NULL, the content of the resource or allocation can be assumed to be lost. If the driver does not need the content of the resource or allocation, setting pDiscarded to NULL might improve performance.

[in] NumAllocations

The number of items in the pResources, HandleList, or pDiscarded members, whichever is not NULL.
