[New for Windows NT 4.0 Service Pack 3.]
The SetupCreateDiskSpaceList function creates a disk-space list.
HDSKSPC SetupCreateDiskSpaceList(
  PVOID Reserved1,  // unused, must be zero
  DWORD Reserved2,  // unused, must be zero
  UINT Flags        // specifies whether to ignore files already on 
                    // the disk
);
 If the function succeeds, it returns a handle to the disk-space list.
If the function fails, it returns NULL. To get extended error information, call GetLastError.
