PFND3D12DDI_RESOLVE_QUERY_DATA callback function (d3d12umddi.h)

The pfnResolveQueryData callback function transforms a previously stored query into an API defined format.

Syntax

PFND3D12DDI_RESOLVE_QUERY_DATA Pfnd3d12ddiResolveQueryData;

void Pfnd3d12ddiResolveQueryData(
  D3D12DDI_HCOMMANDLIST unnamedParam1,
  D3D12DDI_HQUERYHEAP unnamedParam2,
  D3D12DDI_QUERY_TYPE unnamedParam3,
  UINT StartElement,
  UINT ElementCount,
  D3D12DDI_HRESOURCE hDrvDestinationBuffer,
  UINT64 DestinationOffset
)
{...}

Parameters

unnamedParam1

hCommandList

A handle to the driver's data for the command list. The driver uses this region of memory to store internal data structures that are related to its command list.

unnamedParam2

hQueryHeap

The handle of a query heap.

unnamedParam3

QueryType

A query type.

StartElement

The value of the start element.

ElementCount

The element count.

hDrvDestinationBuffer

The handle of a destination buffer.

DestinationOffset

The destination offset.

Return value

None

Remarks

Resolve functionality is used by applications to transform a query result previously stored in a query heap into the API defined format. The resolved data is stored in a buffer. The results can then be consumed by a shader, predication, or mapped and read on the CPU.
