title: C Timer Callback
body: <p>Interested in something similar to JavaScript setTimeout in C on both UNIX and Windows.</p>
  
  <p>Basically, I want:</p>
  
  <pre><code>start_timer(&amp;function_pointer, int time_in_secs)
  </code></pre>
  
  <p>or as close to that as I can get.</p>
  
  <p>Also, something similar to setInterval would be nice (where it calls the callback every n seconds), but that can be implemented using setTimeout :)</p>
