pfnStatePsConstBufCb routine

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

Syntax


PFND3D10DDI_STATE_PS_CONSTBUF_CB pfnStatePsConstBufCb;

void APIENTRY pfnStatePsConstBufCb(
  _In_  D3D10DDI_HRTCORELAYER hRuntimeDevice,
  _In_  UINT Base,
  _In_  UINT Count
)
{ ... }

Parameters

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.

Base [in]

The starting constant buffer to refresh.

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.

Return value

None

Remarks

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

Requirements

Version

Available in Windows Vista and later versions of the Windows operating systems.
