PFND3D10DDI_STATE_VS_CONSTBUF_CB callback function (d3d10umddi.h)

Article

The pfnStateVsConstBufCb function causes the Microsoft Direct3D 10 runtime to refresh the vertex shader stage's bound constant buffers.

Syntax

PFND3D10DDI_STATE_VS_CONSTBUF_CB Pfnd3d10ddiStateVsConstbufCb;

void Pfnd3d10ddiStateVsConstbufCb(
  D3D10DDI_HRTCORELAYER unnamedParam1,
  UINT unnamedParam2,
  UINT unnamedParam3
)
{...}

Parameters

unnamedParam1

hRuntimeDevice [in]

A handle to a context for the core Direct3D 10 runtime. This handle is supplied to the driver in a call to the driver's CreateDevice(D3D10) function.

unnamedParam2

Count [in]

The total number of buffers to refresh. The number can be -1, which specifies that the Direct3D runtime will use its high watermarks to substitute an optimal value (which is typically less than the maximum valid value for Count). However, no non-NULL binding exists in a slot larger than the optimal Count value.

unnamedParam3

Base [in]

The starting constant buffer to refresh.

Return value

None

Remarks

The Base and Count parameters that the driver passes to the pfnStateVsConstBufCb function directly correspond to the StartBuffer and NumBuffers parameters that are passed to the driver's VsSetConstantBuffers function.
