STORAGE_TEMPERATURE_DATA_DESCRIPTOR structure (ntddstor.h)
This structure is used in conjunction with IOCTL_STORAGE_QUERY_PROPERTY to return temperature data from a storage device or adapter.
Syntax
typedef struct _STORAGE_TEMPERATURE_DATA_DESCRIPTOR {
ULONG Version;
ULONG Size;
SHORT CriticalTemperature;
SHORT WarningTemperature;
USHORT InfoCount;
UCHAR Reserved0[2];
ULONG Reserved1[2];
STORAGE_TEMPERATURE_INFO TemperatureInfo[ANYSIZE_ARRAY];
} STORAGE_TEMPERATURE_DATA_DESCRIPTOR, *PSTORAGE_TEMPERATURE_DATA_DESCRIPTOR;
Members
Version
Contains the size of this structure, in bytes. The value of this member will change as members are added to the structure.
Size
Specifies the total size of the data returned, in bytes. This may include data that follows this structure.
CriticalTemperature
Indicates the minimum temperature in degrees Celsius that may prevent normal operation. Exceeding this temperature may result in possible data loss, automatic device shutdown, extreme performance throttling, or permanent damage.
WarningTemperature
Indicates the maximum temperature in degrees Celsius at which the device is capable of operating continuously without degrading operation or reliability.
InfoCount
Specifies the number of *STORAGE_TEMPERATURE_INFO structures reported in TemperatureInfo. More than one set of temperature data may be returned when there are multiple sensors in the drive.
Reserved0[2]
Reserved for future use.
Reserved1[2]
Reserved for future use.
TemperatureInfo[ANYSIZE_ARRAY]
Device temperature data, of type *STORAGE_TEMPERATURE_INFO.
