title: Can you explain in more detail what's the difference between PIPE_READMODE_MESSAGE/PIPE_READMODE_BYTE?
body: <p>Though I've go through the document <a href="http://msdn.microsoft.com/en-us/library/aa365150%28VS.85%29.aspx" rel="noreferrer">here</a>, it still doesn't make sense to me what it is:</p>
  
  <blockquote>
    <p>Data is read from the pipe as a stream
    of messages. This mode can be only
    used if PIPE_TYPE_MESSAGE is also
    specified.</p>
  </blockquote>
