PFND3D12DDI_CALC_PRIVATE_COMMAND_LIST_SIZE_0040 callback function

Description

The CalcPrivateCommandListSize 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 command list.

Parameters

`unnamedParam1`

A handle to the display device (graphics context).

`unnamedParam2`

Pointer to a D3D12DDIARG_CREATE_COMMAND_LIST_0040 structure that describes the parameters that the user-mode display driver uses to calculate the size of the memory region.

Return value

Returns the size of the memory region that the driver requires to create a command list.

Remarks

The driver is only required to implement CalcPrivateCommandListSize if the driver supports the D3D11DDICAPS_COMMANDLISTS_BUILD_2 capability that can be returned in the D3D11DDI_THREADING_CAPS structure from a call to the GetCaps(D3D10_2) function.
