HRESULT Pfnd3dddiSetvertexshaderconst(
  [in] HANDLE hDevice,
       const D3DDDIARG_SETVERTEXSHADERCONST *unnamedParam2,
       const VOID *unnamedParam3
)
{...}

Parameters

[in] hDevice

A handle to the display device (graphics context).

unnamedParam2

pData [in]

A pointer to a D3DDDIARG_SETVERTEXSHADERCONST structure that specifies how to set the vertex shader constant registers.

unnamedParam3

pRegisters [in]

A pointer to a buffer that contains the floating-point values to copy.
