IaSetIndexBuffer routine

The IaSetIndexBuffer function sets an index buffer for an input assembler.

Syntax


PFND3D10DDI_IA_SETINDEXBUFFER IaSetIndexBuffer;

VOID APIENTRY IaSetIndexBuffer(
  _In_  D3D10DDI_HDEVICE hDevice,
  _In_  D3D10DDI_HRESOURCE hBuffer,
  _In_  DXGI_FORMAT Format,
  _In_  UINT Offset
)
{ ... }

Parameters

hDevice [in]

A handle to the display device (graphics context).

hBuffer [in]

A handle to the index buffer to set.

Format [in]

A DXGI_FORMAT-typed value that indicates the pixel format of the index buffer. Only the DXGI_FORMAT_R16_UINT and DXGI_FORMAT_R32_UINT formats are valid; all other formats are invalid.

Offset [in]

The offset, in bytes, into the index buffer.

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

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 will determine that the error is critical. Even if the device was removed, the driver is not required to return D3DDDIERR_DEVICEREMOVED; however, if device removal interfered with the operation of IaSetIndexBuffer (which typically should not happen), the driver can return D3DDDIERR_DEVICEREMOVED.

Requirements

Version

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