       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.
