title: CString::GetBuffer() example
body: <p>I am trying to understand the GetBuffer() function. Looks like it returns you the pointer to the CString, which is confirmed in  <a href="http://msdn.microsoft.com/en-us/library/aa314880%28v=vs.60%29.aspx" rel="noreferrer">msdn GetBuffer()</a>. However, I don't understand the example shown in the <a href="http://msdn.microsoft.com/en-us/library/aa314880%28v=vs.60%29.aspx" rel="noreferrer">msdn GetBuffer()</a>. </p>
  
  <pre><code>LPTSTR p = s.GetBuffer( 10 );
  </code></pre>
  
  <p>Is there a reason why it's 10 inside? Can anyone show me the output of the example?</p>
