  Closes the file referenced by [;;4mIoDevice[0m. It mostly returns [;;4mok[0m,
  except for some severe errors such as out of memory.

  Notice that if option [;;4mdelayed_write[0m was used when opening the
  file, [;;4mclose/1[0m can return an old write error and not even try to
  close the file. See [;;4mopen/2[0m.
