PFND3D12DDI_CHECKEXISITINGRESOURCEALLOCATIONINFO_0022 callback function

Description

The pfnCheckExistingResourceAllocationInfo callback function supports checking existing resource allocation information.

Parameters

`unnamedParam1`

hDevice

A handle to the display device (graphics context).

`unnamedParam2`

hResource

A resource handle.

`unnamedParam3`

pInfo [out]

Remarks

This callback function is part of a two step process of resource creation. After the pfnCheckResourceAllocationInfo callback function, the resource is created. During resource creation, the layout is never _UNDEFINED, since the driver will have returned a resolved texture layout.
