  <p>The freopen() function is used to reassign an existing
  <em>stream</em> to a different file and mode. After a call to this
  function, the given file <em>stream</em> will refer to <em>fname</em>
  with access given by <em>mode</em>. The return value of freopen() is
  the new stream, or <strong>NULL</strong> if there is an error.</p>
