/*! @header IOPM.h
@abstract Defines power management constants and keys used by both in-kernel and user space power management.
@discussion IOPM.h defines a range of power management constants used in several in-kernel and user space APIs. Most significantly, the IOPMPowerFlags used to specify the fields of an IOPMPowerState struct are defined here.
Useful only as a Capability.
- @constant kIOPMSleepCapability
+ @constant kIOPMSleepCapability
Used only by certain IOKit Families (USB). Not defined or used by generic Power Management. Read your family documentation to see if you should define a powerstate using these capabilities.
@constant kIOPMRestartCapability
@constant kIOPMRestart
Used only by certain IOKit Families (USB). Not defined or used by generic Power Management. Read your family documentation to see if you should define a powerstate using these capabilities.
+
+ @constant kIOPMInitialDeviceState
+ Indicates the initial power state for the device. If <code>initialPowerStateForDomainState()</code> returns a power state with this flag set in the capability field, then the initial power change is performed without calling the driver's <code>setPowerState()</code>.
