PMI_METERED_HARDWARE_INFORMATION structure (pmi.h)

  • Article

The PMI_METERED_HARDWARE_INFORMATION structure contains information about one or more power supplies that are monitored by the power meter.

Syntax

typedef struct _PMI_METERED_HARDWARE_INFORMATION {
  ULONG MeteredHardwareCount;
  WCHAR MeteredHardware[ANYSIZE_ARRAY];
} PMI_METERED_HARDWARE_INFORMATION, *PPMI_METERED_HARDWARE_INFORMATION;

Members

MeteredHardwareCount

A value that specifies the number of device identifiers that are returned in the MeteredHardware member.

MeteredHardware[ANYSIZE_ARRAY]

A Unicode string that specifies the name of each device that is powered by the circuit on which the power meter provides measurement data. Individual device paths are delimited by a NULL character, and the whole list is terminated with a double NULL. The format of the device name is \Device\xyz".

Note  For systemwide power meters, this member returns NULL.
 

Remarks

The PMI_METERED_HARDWARE_INFORMATION structure is returned through an IOCTL_PMI_GET_CAPABILITIES I/O control (IOCTL) query request. The input data for this query request is set to the PMI_CAPABILITIES_TYPE enumerator value of PmiMeteredHardware.

If the query request completes successfully, the request returns a PMI_CAPABILITIES structure. The Capabilities member of this structure is formatted as a PMI_METERED_HARDWARE_INFORMATION structure.
