D3DDDICB_OFFERALLOCATIONS structure (d3dumddi.h)

Defines the video memory allocations that the driver offers for reuse. Used with the pfnOfferAllocationsCb function.

Syntax

typedef struct _D3DDDICB_OFFERALLOCATIONS {
  [in] const HANDLE          *pResources;
  [in] const D3DKMT_HANDLE   *HandleList;
  [in] UINT                  NumAllocations;
  [in] D3DDDI_OFFER_PRIORITY Priority;
} D3DDDICB_OFFERALLOCATIONS;

Members

[in] pResources

An array of Direct3D runtime handles to resources to offer.

If the user-mode driver uses the array specified by HandleList to offer a list of allocations, it must set pResources to NULL. Conversely, if the driver uses the array specified by pResources to offer a list of resources, it must set HandleList to NULL.

[in] HandleList

An array of D3DKMT_HANDLE data types that represent kernel-mode handles to allocations to offer.

If resources were created with the D3D10_DDI_BIND_PRESENT flag value set in pCreateResource->BindFlags, offer the resources by their allocation handles, not by their resource handles.

[in] NumAllocations

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

[in] Priority

The priority, of type D3DDDI_OFFER_PRIORITY, with which to offer the allocations for reuse.

Note  Do not set this member to a value of D3DDDI_OFFER_PRIORITY_NONE.
