PFND3DDDI_SETPIXELSHADERCONST callback function (d3dumddi.h)

The SetPixelShaderConst function sets one or more pixel shader constant registers with floating-point values.

Syntax

PFND3DDDI_SETPIXELSHADERCONST Pfnd3dddiSetpixelshaderconst;

HRESULT Pfnd3dddiSetpixelshaderconst(
  [in] HANDLE hDevice,
       const D3DDDIARG_SETPIXELSHADERCONST *unnamedParam2,
       const FLOAT *unnamedParam3
)
{...}

Parameters

[in] hDevice

A handle to the display device (graphics context).

unnamedParam2

pData [in]

A pointer to a D3DDDIARG_SETPIXELSHADERCONST structure that describes how to set the pixel shader constant registers.

unnamedParam3

pRegisters [in]

A pointer to a buffer that contains 4-float vectors to copy.

Return value

SetPixelShaderConst returns S_OK or an appropriate error result if the pixel shader constant registers are not successfully set with floating-point values.
