PFND3DDDI_DELETEVERTEXSHADERDECL callback function

Description

The DeleteVertexShaderDecl function cleans up driver-side resources that are associated with the vertex shader declaration.

Parameters

`hDevice`

A handle to the display device (graphics context).

`unnamedParam2`

hShaderHandle [in]

A handle to the vertex shader declaration object.

Return value

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

Remarks

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