title: Doxygen document C functions in Objective-C projects
body: <p>I am programming a project in Objective-C and I have started to use Doxygen to automatically generate documentation. A significant portion of the project contains basic C functions. Unfortunately Doxygen is not documenting C functions, only Objective-C classes and their methods. I have the functions defined in several header files like so:</p>
  
  <pre><code>BOOL myFunc(void);
  </code></pre>
  
  <p>Which I then have implemented in a .m.</p>
  
  <p>Does Doxygen not detect straight C functions in Objective-C or is there an option I have to turn on? Is my function defined incorrectly for Doxygen?</p>
