CalcPrivateDeferredContextSize routine

The CalcPrivateDeferredContextSize 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 a deferred context.

Syntax


PFND3D11DDI_CALCPRIVATEDEFERREDCONTEXTSIZE CalcPrivateDeferredContextSize;

SIZE_T APIENTRY CalcPrivateDeferredContextSize(
  _In_  D3D10DDI_HDEVICE hDevice,
  _In_  const D3D11DDIARG_CALCPRIVATEDEFERREDCONTEXTSIZE *pCalcPrivateDeferredContextSize
)
{ ... }

Parameters

hDevice [in]

A handle to the display device (graphics context).

pCalcPrivateDeferredContextSize [in]

A pointer to a D3D11DDIARG_CALCPRIVATEDEFERREDCONTEXTSIZE structure that describes the parameters that the user-mode display driver uses to calculate the size of the memory region.

Return value

CalcPrivateDeferredContextSize returns the size of the memory region that the driver requires to create a deferred context.

Remarks

The driver is only required to implement CalcPrivateDeferredContextSize if the driver supports the D3D11DDICAPS_COMMANDLISTS_BUILD_2 capability that can be returned in the D3D11DDI_THREADING_CAPS structure from a call to the GetCaps(D3D10_2) function.

Requirements

Version

CalcPrivateDeferredContextSize is supported beginning with the Windows 7 operating system.

Header

D3d10umddi.h (include D3d10umddi.h)
