title: API documentation: LSOpenURLsWithRole()
body: <p>Recently, starting Preview on a list of gif images produced the error :-</p>
  
  <p><code>LSOpenURLsWithRole() failed with error -600 for the file /Users/uki/repos/gif-fuzzing/test/234.gif.</code></p>
  
  <p>However on opening 234.gif the error could not be reproduced. This error keeps repeating at random intervals of time. I've been searching around for Apple Developer Documentation on what <code>LSOpenURLsWithRole</code> actually does, but I could not find any(which is weird).</p>
  
  <ol>
  <li>Could anyone point me to where the API docs of this function would be?</li>
  <li>Has anyone had a similar error before?</li>
  </ol>
