HsSetConstantBuffers routine

The HsSetConstantBuffers function sets constant buffers for a hull shader.

Syntax


PFND3D10DDI_SETCONSTANTBUFFERS HsSetConstantBuffers;

VOID APIENTRY HsSetConstantBuffers(
  _In_  D3D10DDI_HDEVICE hDevice,
  _In_  UINT StartBuffer,
  _In_  UINT NumBuffers,
  _In_  const D3D10DDI_HRESOURCE *phBuffers
)
{ ... }

Parameters

hDevice [in]

A handle to the display device (graphics context).

StartBuffer [in]

The starting constant buffer to set.

NumBuffers [in]

The total number of buffers to set.

phBuffers [in]

An array of handles to the constant buffers, beginning with the buffer that StartBuffer specifies.

Return value

None

The driver can use the pfnSetErrorCb callback function to set an error code. For more information about setting error codes, see the following Remarks section.

Remarks

Buffers that the HsSetConstantBuffers function specifies are created with the D3D10_BIND_CONSTANT_BUFFER flag.

The driver should not encounter any error, except for D3DDDIERR_DEVICEREMOVED. Therefore, if the driver passes any error, except for D3DDDIERR_DEVICEREMOVED, in a call to the pfnSetErrorCb function, the Direct3D runtime determines that the error is critical. Even if the device is removed, the driver is not required to return D3DDDIERR_DEVICEREMOVED; however, if device removal interferes with the operation of HsSetConstantBuffers (which typically should not happen), the driver can return D3DDDIERR_DEVICEREMOVED.

Requirements

Version

HsSetConstantBuffers is supported beginning with the Windows 7 operating system.
