lfLowerWarningLevel
Double precision floating-point value that defines the lower bound of
the monitor parameter during normal operation. If
MONITOR_WARNING_LEVEL_UNDEFINED is specified, the lower
bound is undefined and not used to determine if the parameter enters
the warning state. This is a requirement for some parameters. See
Remarks.
Return Values:
Returns TRUE if the warning levels were successfully set; otherwise,
FALSE on failure.
Remarks:
Upper and lower warning levels specify the upper and lower bounds
of the monitored parameter during normal operation. If the parameter
deviates from the specified operating bounds, it enters the warning
state. Upper and lower warning levels are set by default and can be
altered using this function.
The monitor level specified in lfUpperWarningLevel and
lfLowerWarningLevele varies depending on the type of parameter
being monitored.
See Hardware Monitor Parameters for type/units.
The upper warning level for MONITOR_ID_BATTERY_VOLTAGE
must be MONITOR_WARNING_LEVEL_UNDEFINED.
The lower warning level for MONITOR_ID_CPU_TEMPERATURE must
be MONITOR_WARNING_LEVEL_UNDEFINED.
Portability:
The function prototype is the same as the RAC6182. However, the
MONITOR _ID parameters are different between the platforms.
