title: Doxygen: Documenting overloaded functions
body: <p>In case I have my documentation separate from my code, how do I help Doxygen distinguish between overloaded functions (what to use in the <code>\fn</code> field)? A single function would be documented like this:</p>
  
  <pre><code>void func() {
  }
  
  /**
      \fn func
      \details Description here.
    */
  </code></pre>
  
  <p>What if I have two functions called <code>func</code>?</p>
  
  <pre><code>void func() {
  }
  
  void func(int i) {
  }
  
  /**
      \fn [What goes here?]
      \details Description here.
    */
  </code></pre>
