Directory-backed Handle?

Hi, In the GHC I/O system, a Handle may be backed by a "device" (IODevice instance) with IODeviceType = Directory There doesn't seem to be any (at least Google search did not give anything) code that uses this; however, what is supposed to be read from such a Handle: newline-separated list of filenames (like in getDirectoryContents), or some sort of serialized FileStatus structures, or anything else?
