title: c++ STL cout source code
body: <p>I want to see source code of STL <code>std::cout</code> function. I looked at iostream, but I've seen only  "extern cout". So, I guess that it's defined somewhere in the library.</p>
  
  <p>I downloaded source code from  <a href="http://www.sgi.com/tech/stl/download.html" rel="nofollow">official site</a></p>
  
  <p>I extracted it and did:</p>
  
  <pre><code>sh@sh-R528-R728:~/desktop/stl$ grep -F * | grep "cout"
  </code></pre>
  
  <p>but I got nothing.</p>
  
  <p>What am I doing wrong? Where is the source code?</p>
