Windows Driver Kit DDI reference (nc-d3dumddi-pfnd3dddi_setindices)

PFND3DDDI_SETINDICES callback function

Description

The SetIndices function sets the current index buffer.

Parameters

`hDevice`

A handle to the display device (graphics context).

`unnamedParam2`

pData [in]

A pointer to a D3DDDIARG_SETINDICES structure that describes parameters for setting the current index buffer.

Return value

SetIndices returns S_OK or an appropriate error result if the index buffer is not successfully set.

Remarks

The Microsoft Direct3D runtime supplies a handle value of zero in the hIndexBuffer member of the D3DDDIARG_SETINDICES structure that is pointed to by the pData parameter to clear the current index buffer. The driver should handle subsequent attempts to draw indexed primitives (before a new current index buffer is established) so that a crash does not occur. The debug version of your driver should display informative messages to the debug output stream when this error condition is detected.
