THERMAL_EVENT structure (powrprof.h)

Contains a thermal event.

Syntax

typedef struct _THERMAL_EVENT {
  ULONG  Version;
  ULONG  Size;
  ULONG  Type;
  ULONG  Temperature;
  ULONG  TripPointTemperature;
  LPWSTR Initiator;
} THERMAL_EVENT, *PTHERMAL_EVENT;

Members

Version

The current structure version level, THERMAL_EVENT_VERSION.

Size

The size of the structure.

Type

One of the thermal event values from Ntpoapi.h: THERMAL_EVENT_SHUTDOWN, THERMAL_EVENT_HIBERNATE, or THERMAL_EVENT_UNSPECIFIED.

Temperature

The temperature, in tenths of a degree Kelvin, that the sensor was at after crossing the trip point (or zero if unknown).

TripPointTemperature

The temperature, in tenths of a degree Kelvin, of the trip point (or zero if unknown).

Initiator

A pointer to a NULL-terminated, wide-character string that identifies the sensor whose threshold was crossed.

Remarks

Drivers use the THERMAL_EVENT structure to specify a thermal event. By calling the PowerReportThermalEvent routine, the operating system can record the thermal event in the system event log.
