title: The function sscanf_s fail when I use several strings
body: <p>I don't understand why the code below fail :</p>
  
  <pre><code>char    toto[54], titi[54]; //I already tried with allocations
  
  sscanf_s(line, "%s-%s", &amp;toto, &amp;titi, sizeof(toto) + sizeof(titi));
  </code></pre>
  
  <p>or</p>
  
  <pre><code>sscanf_s(line, "%s-%s", &amp;toto, &amp;titi, sizeof(toto) + sizeof(titi));
  </code></pre>
  
  <p>My problem is only with strings (float, int, double etc. its ok) and I use Visual 2010.</p>
  
  <p>Does anyone have an idea?
  Thanks a lot in advance for your answer.</p>
