# IO.each_byte (from ruby core) --- ios.each_byte {|byte| block } -> ios ios.each_byte -> an_enumerator --- Calls the given block once for each byte (0..255) in *ios*, passing the byte as an argument. The stream must be opened for reading or an IOError will be raised. If no block is given, an enumerator is returned instead. f = File.new("testfile") checksum = 0 f.each_byte {|x| checksum ^= x } #=> #<File:testfile> checksum #=> 12
