  <para>
   Like Radius requests, each response may contain zero or more attributes.
   After a response has been received successfully by
   <function>radius_send_request</function>, its attributes can be extracted
   one by one using <function>radius_get_attr</function>. Each time
   <function>radius_get_attr</function> is called, it gets the next attribute
   from the current response.
  </para>

  <para>
   Returns an associative array containing the attribute-type and the data, or
   error number &lt;= 0.
