CreateElementLayout routine

The CreateElementLayout function creates an element layout.

Syntax


PFND3D10DDI_CREATEELEMENTLAYOUT CreateElementLayout;

VOID APIENTRY CreateElementLayout(
  _In_  D3D10DDI_HDEVICE hDevice,
  _In_  const D3D10DDIARG_CREATEELEMENTLAYOUT *pCreateElementLayout,
  _In_  D3D10DDI_HELEMENTLAYOUT hElementLayout,
  _In_  D3D10DDI_HRTELEMENTLAYOUT hRTElementLayout
)
{ ... }

Parameters

hDevice [in]

A handle to the display device (graphics context).

pCreateElementLayout [in]

A pointer to a D3D10DDIARG_CREATEELEMENTLAYOUT structure that describes the parameters that the user-mode display driver uses to create an element layout.

hElementLayout [in]

A handle to the driver's private data for the element layout. 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 CalcPrivateElementLayoutSize 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 element layout object.

hRTElementLayout [in]

A handle to the element layout 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 DestroyElementLayout function to destroy the handle that the hElementLayout parameter specifies.

Requirements

Version

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