PFND3D11DDI_CALCPRIVATEDEFERREDCONTEXTSIZE callback function (d3d10umddi.h)
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 Pfnd3d11ddiCalcprivatedeferredcontextsize;
SIZE_T Pfnd3d11ddiCalcprivatedeferredcontextsize(
D3D10DDI_HDEVICE unnamedParam1,
const D3D11DDIARG_CALCPRIVATEDEFERREDCONTEXTSIZE *unnamedParam2
)
{...}
Parameters
unnamedParam1
hDevice [in]
A handle to the display device (graphics context).
unnamedParam2
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.
