PFND3D12DDI_CALC_PRIVATE_SHADER_SIZE 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`

A handle to the display device (graphics context).

`pShaderCode`

Pointer to a shader code.

`unnamedParam3`

A handle to a root signature.

`unnamedParam4`

Pointer to a D3D12DDIARG_STAGE_IO_SIGNATURES structure.

Return value

Returns SIZE_T.
