PMI_THRESHOLD_CONFIGURATION structure (pmi.h)

  • Article

The PMI_THRESHOLD_CONFIGURATION structure contains information about the threshold configuration of the power meter.

Syntax

typedef struct _PMI_THRESHOLD_CONFIGURATION {
  ULONG LowerThreshold;
  ULONG UpperThreshold;
} PMI_THRESHOLD_CONFIGURATION, *PPMI_THRESHOLD_CONFIGURATION;

Members

LowerThreshold

The lower threshold of the power meter, in units of milliwatts (mW).

UpperThreshold

The upper threshold of the power meter, in units of milliwatts (mW).

Remarks

The PMI_THRESHOLD_CONFIGURATION structure specifies the current configuration of the power meter's thresholds. The LowerThreshold and UpperThreshold members specify the lower and upper range of the threshold respectively.

A Power Meter Interface (PMI) event is signaled when the IOCTL_PMI_REGISTER_EVENT_NOTIFY I/O control (IOCTL) request completes when one of the following occurs:

  • Power levels that are monitored by the power meter drop below the LowerThreshold value.
  • Power levels that are monitored by the power meter drop below the UpperThreshold value.

Requirements
