Description

The CalcPrivateResourceSize 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).

Parameters

`unnamedParam1`

hDevice [in]

A handle to the display device (graphics context).

`unnamedParam2`

pCreateResource [in]

A pointer to a D3D10DDIARG_CREATERESOURCE structure that describes the parameters that the user-mode display driver uses to calculate the size of the memory region.

Return value

CalcPrivateResourceSize returns the size of the memory region that the driver requires for creating resources.
