D3DKMT_OFFERALLOCATIONS structure

Defines the video memory allocations that the driver offers for reuse. Used with the D3DKMTOfferAllocations function.

Syntax


typedef struct _D3DKMT_OFFERALLOCATIONS {
  D3DKMT_HANDLE         hDevice;
  D3DKMT_HANDLE         *pResources;
  const D3DKMT_HANDLE   *HandleList;
  UINT                  NumAllocations;
  D3DKMT_OFFER_PRIORITY Priority;
} D3DKMT_OFFERALLOCATIONS;

Members

hDevice

[in] A D3DKMT_HANDLE data type that represents a kernel-mode handle to the device that created the allocations.

pResources

[in] 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.

HandleList

[in] 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.

NumAllocations

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

Priority

[in] The priority, of type D3DKMT_OFFER_PRIORITY, with which to offer the allocations for reuse.
