# class EOFError

Raised by some `IO` operations when reaching the end of file. Many `IO` methods exist in two forms,

one that returns `nil` when the end of file is reached, the other raises `EOFError`.

`EOFError` is a subclass of `IOError`.

    file = File.open("/etc/hosts")
    file.read
    file.gets     #=> nil
    file.readline #=> EOFError: end of file reached
    file.close
