PFND3D10DDI_IA_SETTOPOLOGY callback function (d3d10umddi.h)
The IaSetTopology function sets the primitive topology to enable drawing for the input assembler.
Syntax
PFND3D10DDI_IA_SETTOPOLOGY Pfnd3d10ddiIaSettopology;
void Pfnd3d10ddiIaSettopology(
D3D10DDI_HDEVICE unnamedParam1,
D3D10_DDI_PRIMITIVE_TOPOLOGY unnamedParam2
)
{...}
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.
Return value
None
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.
