Subject: [ruby-talk:12321] Reading a binary file / writing binary data to a file


I'm having troubles while reading binary file with under 
Windows. Probably, I'm forgetting something while opening
a file but I can't figure out what.

Currently I'm using: ruby 1.6.2 (2000-11-04) [i386-mingw32]
under Windows NT.

The following code opens a file with binary data. Although
the size of binaryfile.dat is a few hundred bytes it only
reads one byte. There is no difference in using the methods 
getc, gets or sysread.

  File.open ("binaryfile.dat", "r") { |f|
    while ch = f.getc
      puts "read a character: #{ch}"
    end
  }

Also writing binary data to file causes problems. Note,
everything works fine while reading plain text.

Please help me.


Regards,
Paul.
