function session_api_get_sid() {
  if (!session_api_available()) {
    return FALSE;
  }
  if (!is_numeric($_SESSION['session_api_id'])) {

    // first, check if id exists in db
    $sid = db_result(db_query("SELECT sid FROM {session_api} WHERE session_id = '%s'", session_id()));
    if (!$sid) {

      // no sid exists, create new one
      $sid = db_next_id('{session_api}_sid');
      db_query("INSERT INTO {session_api} (sid, session_id) VALUES (%d, '%s')", $sid, session_id());
    }
    $_SESSION['session_api_id'] = $sid;
