IaSetTopology routine

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

Syntax


PFND3D10DDI_IA_SETTOPOLOGY IaSetTopology;

VOID APIENTRY IaSetTopology(
  _In_  D3D10DDI_HDEVICE hDevice,
  _In_  D3D10_DDI_PRIMITIVE_TOPOLOGY PrimitiveTopology
)
{ ... }

Parameters

hDevice [in]

A handle to the display device (graphics context).

PrimitiveTopology [in]

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

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 IaSetTopology (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.
