EMI_METADATA_V1 structure (emi.h)
The EMI_METADATA structure provides metadata about a device that supports the Energy Metering Interface (EMI) interface, such as the hardware model and hardware revision.
Syntax
typedef struct {
EMI_MEASUREMENT_UNIT MeasurementUnit;
WCHAR HardwareOEM[EMI_NAME_MAX];
WCHAR HardwareModel[EMI_NAME_MAX];
USHORT HardwareRevision;
USHORT MeteredHardwareNameSize;
WCHAR MeteredHardwareName[ANYSIZE_ARRAY];
} EMI_METADATA_V1;
Members
MeasurementUnit
An EMI_MEASUREMENT_UNIT that specifies the unit of energy measurements that can be obtained from the device by calling IOCTL_EMI_GET_MEASUREMENT. In devices that support EMI_VERSION_V1, the only supported unit is EmiMeasurementUnitPicowattHours.
HardwareOEM[EMI_NAME_MAX]
A null-terminated, Unicode string that contains the name of the OEM.
HardwareModel[EMI_NAME_MAX]
A null-terminated, Unicode string that specifies the device model.
HardwareRevision
A value that specifies the current revision of the device.
MeteredHardwareNameSize
The size of MeteredHardwareName in bytes, including the null terminator.
MeteredHardwareName[ANYSIZE_ARRAY]
A null-terminated, Unicode string that specifies the metered hardware name.
Remarks
This structure is returned through a successful completion of an IOCTL_EMI_GET_METADATA IOCTL request.
