xfnts_update 方法

RGM 将调用 Update 方法通知运行资源其特性已被更改。唯一可以为 xfnts 数据服务更改的特性与故障监视器有关，因此，每当更新特性时，xfnts_update 方法都将调用 scds_pmf_restart_fm() 来重启该故障监视器。

* check if the Fault monitor is already running and if so stop
   * and restart it. The second parameter to scds_pmf_restart_fm()
   * uniquely identifies the instance of the fault monitor that needs
   * to be restarted.
   */

   scds_syslog(LOG_INFO, "Restarting the fault monitor.");
   result = scds_pmf_restart_fm(scds_handle, 0);
   if (result != SCHA_ERR_NOERR) {
      scds_syslog(LOG_ERR,
          "Failed to restart fault monitor.");
      /* Free up all the memory allocated by scds_initialize */
      scds_close(&scds_handle);
      return (1);
   }

   scds_syslog(LOG_INFO,
   "Completed successfully.");

如果存在多个实例，scds_pmf_restart_fm() 的第二个参数将唯一标识要重启的故障监视器的实例。样例中的值 0 表明该故障监视器只有一个实例。
