The functions exported by the HardwareMonitor driver are listed below.
hm_GetMonitorLevel
This function gets the value of monitored parameter. It is prototyped in
HardwareMonitorAPI.h.
Syntax
#include
#include
BOOL hm_GetMonitorLevel (DWORD dwMonitorID, double *plfMonitorLevel)
Remarks
This function queries the hardware monitor for the value of the
parameter specified with dwMonitorID. The value is returned as a
double precision float in *plfMonitorLevel. The units vary depending on
the parameter.
Note that there are no readable values associated with the power fail
monitor.
Parameter Description
dwMonitorID ID of monitored parameter whose current value is
being queried. Note that only one monitored
parameter can be specified. Possible values are
represented by macros defined in
HardwareMonitorAPI.h as follows:
MONITOR_ID_SUPPLY_3V
MONITOR_ID_SUPPLY_5V
MONITOR_ID_SUPPLY_12V
MONITOR_ID_SUPPLY_BATTERY
MONITOR_ID_TEMPERATURE_BOARD
plfMonitorLevel Pointer to an application-allocated double precision
floating point value which will receive the specified
monitor's current level. Power supply values are
given in units of voltage. Temperature values are
given in units of degrees Celsius.
Return Value
Returns TRUE if the query succeeded. FALSE is returned if the query
failed.
Portability
This function is specific to the RAC6182 hardware.
