  _In_  HANDLE hDevice,
  _In_  const D3DDDIARG_SETPIXELSHADERCONST *pData,
  _In_  const FLOAT *pRegisters
)
{ ... }

Parameters

hDevice [in]

A handle to the display device (graphics context).

pData [in]

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

pRegisters [in]

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