Description

The CalcPrivateBlendStateSize 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 blend state.

Parameters

`unnamedParam1`

hDevice [in]

A handle to the display device (graphics context).

`unnamedParam2`

pBlendDesc [in]

A pointer to a D3D10_DDI_BLEND_DESC structure that describes the parameters that the user-mode display driver uses to calculate the size of the memory region.

Return value

CalcPrivateBlendStateSize returns the size of the memory region that the driver requires for creating a blend state.
