D3D12DDI_HRESOURCE unnamedParam2,
D3D12DDI_RESOURCE_ALLOCATION_INFO_0022 *unnamedParam3
)
{...}

A handle to the display device (graphics context).
unnamedParam2
hResource
A resource handle.
unnamedParam3

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.
