PFND3DDDI_SETVERTEXSHADERCONSTB callback function (d3dumddi.h)
The SetVertexShaderConstB function sets one or more vertex shader constant registers with Boolean values.
Syntax
PFND3DDDI_SETVERTEXSHADERCONSTB Pfnd3dddiSetvertexshaderconstb;
HRESULT Pfnd3dddiSetvertexshaderconstb(
[in] HANDLE hDevice,
const D3DDDIARG_SETVERTEXSHADERCONSTB *unnamedParam2,
const BOOL *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 BOOL values to copy.
