Windows Driver Kit DDI reference (nc-d3d10umddi-pfnd3d10ddi_ia_settopology)

PFND3D10DDI_IA_SETTOPOLOGY callback function

Description

The IaSetTopology function sets the primitive topology to enable drawing for the input assembler.

Parameters

`unnamedParam1`

hDevice [in]

A handle to the display device (graphics context).

`unnamedParam2`

PrimitiveTopology [in]

A D3D10_DDI_PRIMITIVE_TOPOLOGY-typed value that indicates the primitive topology to set.

Remarks

The driver can use the pfnSetErrorCb callback function to set an error code.

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 IaSetTopology (which typically should not happen), the driver can return D3DDDIERR_DEVICEREMOVED.
