title: Any way to view doc for c API in Xcode?
body: <p>I suddenly found Xcode have very poo support for view the C API docs.</p>
  
  <p>Suppose if you want to find the definition for <code>fopen</code>, you can't find any meaningful info for this function expected the declare.</p>
  
  <p>So any workaround for this?</p>
  
  <hr>
  
  <p>Edit according to Mark Szymczyk's  suggestion.  </p>
  
  <p>My problem is when I <code>Option</code> click the function, it just show this function is declare in <code>stdio.h</code>, no more explanation to this function like other cocoa APIs.</p>
  
  <p>And when I search in the  documentation viewer, it shows something like this, this will cost a little time to figure out it.</p>
