PFND3D11DDI_CALCPRIVATEUNORDEREDACCESSVIEWSIZE callback function (d3d10umddi.h)
The CalcPrivateUnorderedAccessViewSize function determines the size of the user-mode display driver's private region of memory (that is, the size of internal driver structures, not the size of the resource video memory) for an unordered access view.
Syntax
PFND3D11DDI_CALCPRIVATEUNORDEREDACCESSVIEWSIZE Pfnd3d11ddiCalcprivateunorderedaccessviewsize;
SIZE_T Pfnd3d11ddiCalcprivateunorderedaccessviewsize(
D3D10DDI_HDEVICE unnamedParam1,
const D3D11DDIARG_CREATEUNORDEREDACCESSVIEW *unnamedParam2
)
{...}
Parameters
unnamedParam1
hDevice [in]
A handle to the display device (graphics context).
unnamedParam2
pCreateUnorderedAccessView [in]
A pointer to a D3D11DDIARG_CREATEUNORDEREDACCESSVIEW structure that describes the parameters that the user-mode display driver uses to calculate the size of the memory region.
Return value
CalcPrivateUnorderedAccessViewSize returns the size of the memory region that the driver requires to create an unordered access view.
