title: Handling two different functions with the same name in Doxygen
body: <p>I have a C project which contains two functions with the same name, but each is within a different group/module (<code>@defgroup</code>).</p>
  
  <p>These functions each compile into a different binary, but I need the documentation to be closely cross-referenced, so I need to refer (<code>@ref</code>) to these functions (among other places) from each other's module.</p>
  
  <p>When I do simple <code>@ref name-of-the-function</code>, it always links to the one which resides in file which is earlier in the file tree. How can I link to the other one?</p>
