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.

Requirements

Version

Available in Windows Vista and later versions of the Windows operating systems.
