Windows Driver Kit DDI reference (nc-d3d10umddi-pfnd3d11_1ddi_calcprivateshadersize)

PFND3D11_1DDI_CALCPRIVATESHADERSIZE callback function

Description

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 shader.

Parameters

`unnamedParam1`

hDevice [in]

A handle to the display device (graphics context).

`pShaderCode`

A pointer to an array of CONST UINT tokens that make up the shader code.

`unnamedParam3`

pSignatures [in]

A pointer to a D3D11_1DDIARG_STAGE_IO_SIGNATURES structure that makes up the shader's signature.

Return value

The size of the memory region that the driver requires for creating a shader.
