CreateRasterizerState routine

The CreateRasterizerState function creates a rasterizer state.

Syntax


PFND3D10DDI_CREATERASTERIZERSTATE CreateRasterizerState;

VOID APIENTRY CreateRasterizerState(
  _In_       D3D10DDI_HDEVICE            hDevice,
  _In_ const D3D10_DDI_RASTERIZER_DESC   *pRasterizerDesc,
  _In_       D3D10DDI_HRASTERIZERSTATE   hRasterizerState,
  _In_       D3D10DDI_HRTRASTERIZERSTATE hRTRasterizerState
)
{ ... }

Parameters

hDevice [in]

A handle to the display device (graphics context).

pRasterizerDesc [in]

A pointer to a D3D10_DDI_RASTERIZER_DESC structure that describes the parameters that the user-mode display driver uses to create a rasterizer state.

hRasterizerState [in]

A handle to the driver's private data for the rasterizer state. The driver returns the size, in bytes, of the memory region that the Microsoft Direct3D runtime must allocate for the private data from a call to the driver's CalcPrivateRasterizerStateSize function. The handle is really just a pointer to a region of memory, the size of which the driver requested. The driver uses this region of memory to store internal data structures that are related to its rasterizer state object.

hRTRasterizerState [in]

A handle to the rasterizer state that the driver should use anytime it calls back into the Direct3D runtime.

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 can pass E_OUTOFMEMORY (if the driver runs out of memory) or D3DDDIERR_DEVICEREMOVED (if the device has been removed) in a call to the pfnSetErrorCb function. The Direct3D runtime will determine that any other errors are critical. If the driver passes any errors, including D3DDDIERR_DEVICEREMOVED, the Direct3D runtime will determine that the handle is invalid; therefore, the runtime will not call the DestroyRasterizerState function to destroy the handle that the hRasterizerState parameter specifies.

The user-mode display driver is not required to create more than 4,096 unique instances of rasterizer-state objects on a device at a time.

Requirements

Target platform

Desktop

Version

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