class IO

Augment the IO class to allow it to determine if an input object has data waiting and to add a binread instance method which will read external input as binary, then close the file.

Public Instance Methods

# File buryspam.rb, line 136
def binread
  binmode

Determine if there is input available in the IO stream. Uses both select and getc. Returns true if there is input waiting, false otherwise. Used to determine if $stdin has input waiting.

# File buryspam.rb, line 127
def has_input?
  if IO.select([self], nil, nil, 1).nil? || (byte = getbyte).nil?
    return false
  end
  ungetbyte(byte)
  true
end
