title: Passing variable arguments to makecontext function
body: <p>I want to pass variable arguments to <code>makecontext</code> function as follows.</p>
  <pre><code>void a(...)
  { 
   ....
   makecontext( &amp;stack, &amp;func, ?, ? );
   ....
  }
  </code></pre>
  <p>In the third parameter (<code>?</code>), I should have the number of variable arguments, while in the next <code>?</code>, I should have all the arguments. How can this be done?</p>
