PFND3DWDDM1_3DDI_UPDATETILEMAPPINGS callback function (d3d10umddi.h)

Updates mappings of tile locations in tiled resources to memory locations in a tile pool.

Syntax

PFND3DWDDM1_3DDI_UPDATETILEMAPPINGS Pfnd3dwddm13DdiUpdatetilemappings;

void Pfnd3dwddm13DdiUpdatetilemappings(
  D3D10DDI_HDEVICE hDevice,
  D3D10DDI_HRESOURCE hTiledResource,
  UINT NumTiledResourceRegions,
  const D3DWDDM1_3DDI_TILED_RESOURCE_COORDINATE *pTiledResourceRegionStartCoords,
  const D3DWDDM1_3DDI_TILE_REGION_SIZE *pTiledResourceRegionSizes,
  D3D10DDI_HRESOURCE hTilePool,
  UINT NumRanges,
  const UINT *pRangeFlags,
  const UINT *pTilePoolStartOffsets,
  const UINT *pRangeTileCounts,
  UINT Flags
)
{...}

Parameters

hDevice

A handle to the display device (graphics context).

hTiledResource

A handle to the tiled resource.

NumTiledResourceRegions

The number of tiled resource regions.

pTiledResourceRegionStartCoords

An array of D3DWDDM1_3DDI_TILED_RESOURCE_COORDINATE structures that describe the starting coordinates of the tiled resource regions. The NumTiledResourceRegions parameter specifies the number of D3DWDDM1_3DDI_TILED_RESOURCE_COORDINATE structures in the array.

pTiledResourceRegionSizes

An array of D3DWDDM1_3DDI_TILE_REGION_SIZE structures that describe the sizes of the tiled resource regions. The NumTiledResourceRegions parameter specifies the number of D3DWDDM1_3DDI_TILE_REGION_SIZE structures in the array.

hTilePool

A handle to the tile pool.

NumRanges

The number of tile-pool ranges.

pRangeFlags

An array of values that describe each tile-pool range. The NumRanges parameter specifies the number of values in the array. Each value can be a combination of values of type D3DWDDM1_3DDI_TILE_RANGE_FLAG combined by using a bitwise OR operation.

pTilePoolStartOffsets

An array of offsets into the tile pool. These are zero-based tile offsets, counting in tiles (not bytes).

pRangeTileCounts

An array of values that specify the number of tiles in each tile-pool range. The NumRanges parameter specifies the number of values in the array.

Flags

A combination of D3DWDDM1_3DDI_TILE_MAPPING_FLAG values that are combined by using a bitwise OR operation.

Return value

None

Remarks

The driver can use the pfnSetErrorCb callback function to set an error code. The driver can set E_INVALIDARG if a required input parameter does not exist or is NULL.
