title: Syntax highlighting of C function calls in emacs
body: <p>I use a custom syntax highlighting theme for C in emacs, but I'm missing the possibility of highlighting function calls. For example:</p>
  
  <pre><code>int func(int foo)
  {
      return foo;
  }
  
  void main()
  {
      int bar = func(3);
  }
  </code></pre>
  
  <p>Is there any way to highlight the call to "func" in this example?
  It doesn't matter if macros are highlighted too. Keywords like if, switch or sizeof should not match.</p>
  
  <p>Thanks!</p>
