POWER_LIMIT_ATTRIBUTES structure (ntpoapi.h)

The POWER_LIMIT_ATTRIBUTES structure describes the attributes of each power limit type.

Syntax

typedef struct _POWER_LIMIT_ATTRIBUTES {
  POWER_LIMIT_TYPES Type;
  ULONG             DomainId;
  ULONG             MaxValue;
  ULONG             MinValue;
  ULONG             MinTimeParameter;
  ULONG             MaxTimeParameter;
  ULONG             DefaultACValue;
  ULONG             DefaultDCValue;
  union {
    struct {
      ULONG SupportTimeParameter : 1;
      ULONG Reserved : 31;
    };
    ULONG AsUlong;
  } Flags;
} POWER_LIMIT_ATTRIBUTES, *PPOWER_LIMIT_ATTRIBUTES;

Members

Type

Indicates which POWER_LIMIT_TYPES this attribute is associated with.

DomainId

Indicates which ___domain this attribute is associated with.

MaxValue

The maximum supported value (inclusive), unit is mW for power, mA for current.

MinValue

The minimum supported value (inclusive), unit is mW for power, mA for current.

MinTimeParameter

The minimum supported time parameter (inclusive), unit is microsecond.

MaxTimeParameter

The maximum supported time parameter (inclusive), unit is microsecond.

DefaultACValue

The default AC value, unit is mW for power, mA for current, microsecond for time parameters.

DefaultDCValue

The default DC value, unit is mW for power, mA for current, microsecond for time parameters.

Flags

Defines the Flags union.

Flags.SupportTimeParameter

Set to 1 if this limit supports time parameter.

Flags.Reserved

Reserved

Flags.AsUlong

Defines the AsULong member of the Flags union.

Remarks

Each instance of POWER_LIMIT_ATTRIBUTES is associated with one ___domain and one type. For example, if one power limit device has 2 domains: ___domain 0 supports PowerLimitContinuous, ___domain 1 supports PowerLimitContinuous and PowerLimitPreemptive.
