CsSetUnorderedAccessViews routine

The CsSetUnorderedAccessViews function sets unordered access view (UAV) objects for a compute shader.



VOID APIENTRY CsSetUnorderedAccessViews(
  _In_       D3D10DDI_HDEVICE              hDevice,
  _In_       UINT                          Offset,
  _In_       UINT                          NumViews,
  _In_ const D3D11DDI_HUNORDEREDACCESSVIEW *phUnorderedAccessView,
  _In_ const UINT                          *pUAVInitialCounts
{ ... }


hDevice [in]

A handle to the display device (graphics context).

Offset [in]

The offset to the first view to set.

NumViews [in]

The total number of views to set.

phUnorderedAccessView [in]

An array of handles to the driver's private data for unordered access view objects to set. Note that some handle values can be NULL.

pUAVInitialCounts [in]

An array of append and consume buffer offsets. A value of -1 indicates that the current offset should be kept. Any other values set the hidden counter for that appendable and consumable UAV. pUAVInitialCounts is only relevant for UAVs of the phUnorderedAccessView array that were created with either D3D11_DDI_BUFFER_UAV_FLAG_APPEND or D3D11_DDI_BUFFER_UAV_FLAG_COUNTER specified in the Flags member of the D3D11DDIARG_BUFFER_UNORDEREDACCESSVIEW structure when the UAV was created; otherwise, the argument is ignored.

Return value


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.


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 Microsoft Direct3D runtime determines that the error is critical. Even if the device is removed, the driver is not required to return D3DDDIERR_DEVICEREMOVED; however, if device removal interferes with the operation of CsSetUnorderedAccessViews (which typically should not happen), the driver can return D3DDDIERR_DEVICEREMOVED.


Target platform


CsSetUnorderedAccessViews is supported beginning with the Windows 7 operating system.
