PFND3D10DDI_DESTROYELEMENTLAYOUT callback function

The DestroyElementLayout function destroys the specified element layout object. The element layout object can be destoyed only if it is not currently bound to a display device.

Syntax

PFND3D10DDI_DESTROYELEMENTLAYOUT Pfnd3d10ddiDestroyelementlayout;

void Pfnd3d10ddiDestroyelementlayout(
  D3D10DDI_HDEVICE Arg1,
  D3D10DDI_HELEMENTLAYOUT Arg2
)
{...}

Parameters

Arg1

hDevice [in]

A handle to the display device (graphics context).

Arg2

hElementLayout [in]

A handle to the driver's private data for the element layout object to destroy. The Microsoft Direct3D runtime will free the memory region that it previously allocated for the object. Therefore, the driver can no longer access this memory region.

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