DXGKARG_CREATEALLOCATION structure
The DXGKARG_CREATEALLOCATION structure describes how the display miniport driver should create allocations.
Syntax
typedef struct _DXGKARG_CREATEALLOCATION { const VOID *pPrivateDriverData; UINT PrivateDriverDataSize; UINT NumAllocations; DXGK_ALLOCATIONINFO *pAllocationInfo; HANDLE hResource; DXGK_CREATEALLOCATIONFLAGS Flags; } DXGKARG_CREATEALLOCATION;
Members
- pPrivateDriverData
-
[in] A pointer to a block of private data that is passed from the user-mode display driver to the display miniport driver. This member is typically used to provide data for a group of allocations. Note that this member is distinct from the pPrivateDriverData members of the DXGK_ALLOCATIONINFO structures in the array that pAllocationInfo specifies. You can set private data for this member in addition to private data for each allocation.
- PrivateDriverDataSize
-
[in] The size, in bytes, of the private data that pPrivateDriverData points to.
- NumAllocations
-
[in] The number of elements in the array that pAllocationInfo specifies, which represents the number of allocations to create.
- pAllocationInfo
-
[in/out] An array of DXGK_ALLOCATIONINFO structures that describe the allocations to create.
- hResource
-
[in/out] A handle to a resource. The display miniport driver can set this handle to a value that the Microsoft DirectX graphics kernel subsystem can subsequently pass in driver calls and that refers to information for the allocations. If the resource was already created by a previous DxgkDdiCreateAllocation call, this member contains the handle that the driver previously returned.
- Flags
-
[in] A DXGK_CREATEALLOCATIONFLAGS structure that identifies how to create allocations. Setting all of the bit-field flags to 0 indicates that allocations belong to the device and not to a particular resource.
