Enumeration Type Documentation

PsmBatteryVoltageState

enum PsmBatteryVoltageState

Enumerator
PsmBatteryVoltageState_NeedsShutdown	Power state should transition to shutdown.
PsmBatteryVoltageState_NeedsSleep	Power state should transition to sleep.
PsmBatteryVoltageState_NoPerformanceBoost	Performance boost modes cannot be entered.
PsmBatteryVoltageState_Normal	Everything is normal.

PsmChargerType

enum PsmChargerType

Enumerator
PsmChargerType_Unconnected	No charger.
PsmChargerType_EnoughPower	Full supported power.
PsmChargerType_LowPower	Lower power supported USB-PD mode.
PsmChargerType_NotSupported	No common supported USB-PD modes.

Function Documentation

psmBindStateChangeEvent()

Result psmBindStateChangeEvent	(	PsmSession *	s,
		bool	ChargerType,
		bool	PowerSupply,
		bool	BatteryVoltage
	)

Wrapper func which opens a PsmSession and handles event setup.

Note

Uses the actual BindStateChangeEvent cmd internally.

The event is not signalled on BatteryChargePercentage changes.

Parameters

[out]	s	PsmSession object.
[in]	ChargerType	Passed to SetChargerTypeChangeEventEnabled.
[in]	PowerSupply	Passed to SetPowerSupplyChangeEventEnabled.
[in]	BatteryVoltage	Passed to SetBatteryVoltageStateChangeEventEnabled.
