Windows Driver Kit DDI reference (nc-d3dumddi-pfnd3dddi_deletevertexshaderfunc)

PFND3DDDI_DELETEVERTEXSHADERFUNC callback function

Description

The DeleteVertexShaderFunc function cleans up driver-side resources that are associated with vertex shader code.

Parameters

`hDevice`

A handle to the display device (graphics context).

`unnamedParam2`

hShaderHandle [in]

A handle to the vertex shader code object.

Return value

DeleteVertexShaderFunc returns S_OK or an appropriate error result if the vertex shader code object is not successfully cleaned up.

Remarks

The DeleteVertexShaderFunc function notifies the driver about the deletion of the vertex shader code object that the CreateVertexShaderFunc function created. The driver can then clean up any driver-side resources that are associated with the vertex shader code.
