CreateUnorderedAccessView routine

The CreateUnorderedAccessView function creates an unordered access view.

Syntax


PFND3D11DDI_CREATEUNORDEREDACCESSVIEW CreateUnorderedAccessView;

VOID APIENTRY CreateUnorderedAccessView(
  _In_  D3D10DDI_HDEVICE hDevice,
  _In_  const D3D11DDIARG_CREATEUNORDEREDACCESSVIEW *pCreateUnorderedAccessView,
  _In_  D3D11DDI_HUNORDEREDACCESSVIEW hUnorderedAccessView,
  _In_  D3D11DDI_HRTUNORDEREDACCESSVIEW hRTUnorderedAccessView
)
{ ... }

Parameters

hDevice [in]

A handle to the display device (graphics context).

pCreateUnorderedAccessView [in]

A pointer to a D3D11DDIARG_CREATEUNORDEREDACCESSVIEW structure that describes the parameters that the user-mode display driver uses to create an unordered access view.

hUnorderedAccessView [in]

A handle to the driver's private data for the unordered access view. 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 CalcPrivateUnorderedAccessViewSize function. The handle is 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 unordered access view object.

hRTUnorderedAccessView [in]

A handle to the unordered access view that the driver should use when 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 might run out of memory. Therefore, the driver can pass E_OUTOFMEMORY or D3DDDIERR_DEVICEREMOVED in a call to the pfnSetErrorCb function. The Direct3D runtime determines that any other errors are critical. If the driver passes any errors, which includes D3DDDIERR_DEVICEREMOVED, the Direct3D runtime determines that the handle is invalid; therefore, the runtime does not call the DestroyUnorderedAccessView function to destroy the handle that the hUnorderedAccessView parameter specifies.

Requirements

Version

CreateUnorderedAccessView is supported beginning with the Windows 7 operating system.
