The manual says this:

  Unless otherwise stated, all I/O functions return nil on failure (plus
  an error message as a second result and a system-dependent error code
  as a third result) and some value different from nil on success.

  (http://www.lua.org/manual/5.3/manual.html#6.8)

What else could it say?
