## `xfnts_monitor_stop` Method

Because the `xfnts_monitor_start` method uses `scds_pmf_start()` to start the monitor daemon under the PMF, `xfnts_monitor_stop` uses `scds_pmf_stop()`to stop the monitor daemon.

Note - The first call in `xfnts_monitor_stop` is to `scds_initialize()`, which performs some necessary housekeeping functions. `scds_initialize()` Function and the `scds_initialize`(3HA) man page contain more information.

The `xfnts_monitor_stop()` method calls the `mon_stop` method, which is defined in the `xfnts.c` file, as follows:

    scds_syslog_debug(DBG_LEVEL_HIGH,
          "Calling scds_pmf_stop method");

       err = scds_pmf_stop(scds_handle, SCDS_PMF_TYPE_MON,
           SCDS_PMF_SINGLE_INSTANCE, SIGKILL,
           scds_get_rs_monitor_stop_timeout(scds_handle));

       if (err != SCHA_ERR_NOERR) {
          scds_syslog(LOG_ERR,
              "Failed to stop fault monitor.");
          return (1);
       }

       scds_syslog(LOG_INFO,
           "Stopped the fault monitor.");

       return (SCHA_ERR_NOERR); /* Successfully stopped monitor */
    }

Note the following points about the call in `svc_mon_stop()` to the `scds_pmf_stop()` function:

- The `SCDS_PMF_TYPE_MON` argument identifies the program to stop as a fault monitor. This method can also stop a data service or some other type of application.

- The `SCDS_PMF_SINGLE_INSTANCE` argument identifies this as a single-instance resource.

- The `SIGKILL` argument identifies the signal to use to stop the resource instance. If this signal fails to stop the instance, `scds_pmf_stop()` returns with a timeout error. See the `scds_pmf_stop`(3HA) man page for details.

- The timeout value is that of the `Monitor_stop_timeout` property of the resource.

Note - Before it exits, the `xfnts_monitor_stop` method calls `scds_close()` to reclaim resources that were allocated by `scds_initialize()`. `scds_initialize()` Function and the `scds_close`(3HA) man page contain more information.
