SIZE_T APIENTRY CalcPrivateQuerySize(
  _In_  D3D10DDI_HDEVICE hDevice,
  _In_  const D3D10DDIARG_CREATEQUERY *pCreateQuery
)
{ ... }

Parameters

hDevice [in]

A handle to the display device (graphics context).

pCreateQuery [in]

A pointer to a D3D10DDIARG_CREATEQUERY structure that describes the parameters that the user-mode display driver uses to calculate the size of the memory region.
