View the official Windows Driver Kit DDI referenceNo description available.
Describes video memory resources that are to be reclaimed and that the user-mode display driver previously offered for reuse. Used with the pfnReclaimAllocationsCb function.
pResources [in]A pointer to an array of handles to the resources that are to be reclaimed.
If pResources is not NULL, the HandleList member must be NULL.
Note If resources were created with the D3D10_DDI_BIND_PRESENT flag value set in pCreateResource->BindFlags, the driver must not use the pResources member to reclaim by resource handles. Instead, the driver must reclaim the resources by using allocation handles specified by HandleList.
HandleList [in]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.
pDiscarded [out]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.
NumAllocations [in]The number of items in the pResources, HandleList, or pDiscarded members, whichever is not NULL.
