D3DKMT_OFFERALLOCATIONS structure (d3dkmthk.h)
Defines the video memory allocations that the driver offers for reuse. Used with the D3DKMTOfferAllocations function.
Syntax
typedef struct _D3DKMT_OFFERALLOCATIONS {
[in] D3DKMT_HANDLE hDevice;
[in] D3DKMT_HANDLE *pResources;
[in] const D3DKMT_HANDLE *HandleList;
[in] UINT NumAllocations;
[in] D3DKMT_OFFER_PRIORITY Priority;
D3DKMT_OFFER_FLAGS Flags;
} D3DKMT_OFFERALLOCATIONS;
Members
[in] hDevice
A D3DKMT_HANDLE data type that represents a kernel-mode handle to the device that created the allocations.
[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 D3DKMT_OFFER_PRIORITY, with which to offer the allocations for reuse.
Flags
Flag options.
