PFND3D10DDI_DRAWINDEXEDINSTANCED callback function (d3d10umddi.h)

The DrawIndexedInstanced function draws particular instances of indexed primitives.

Syntax

PFND3D10DDI_DRAWINDEXEDINSTANCED Pfnd3d10ddiDrawindexedinstanced;

void Pfnd3d10ddiDrawindexedinstanced(
  D3D10DDI_HDEVICE unnamedParam1,
  UINT unnamedParam2,
  UINT unnamedParam3,
  UINT unnamedParam4,
  INT unnamedParam5,
  UINT unnamedParam6
)
{...}

Parameters

unnamedParam1

hDevice [in]

A handle to the display device (graphics context).

unnamedParam2

IndexCountPerInstance [in]

The number of indexes per instance of the index buffer that indexes are read from to draw the primitives.

unnamedParam3

InstanceCount [in]

The number of instances of the index buffer that indexes are read from to draw the primitives.

unnamedParam4

StartIndexLocation [in]

The first index in the index buffer that indexes are read from to draw the primitives.

unnamedParam5

BaseVertexLocation [in]

The number that should be added to each index that is referenced by the various primitives to determine the actual index of the vertex elements in each vertex stream.

unnamedParam6

StartInstanceLocation [in]

The first instance of the index buffer that indexes are read from to draw the primitives.

Return value

None

Remarks

The driver can use the pfnSetErrorCb callback function to set an error code.

The driver should not encounter any error, except for D3DDDIERR_DEVICEREMOVED. Therefore, if the driver passes any error, except for D3DDDIERR_DEVICEREMOVED, in a call to the pfnSetErrorCb function, the Direct3D runtime will determine that the error is critical. Even if the device was removed, the driver is not required to return D3DDDIERR_DEVICEREMOVED; however, if device removal interfered with the operation of DrawIndexedInstanced (which typically should not happen), the driver can return D3DDDIERR_DEVICEREMOVED.
