[IsPwrShutdownAllowed is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions. See Remarks.]
Determines whether the computer supports the soft off power state.
Syntax
BOOLEAN IsPwrShutdownAllowed();
Return value
If the computer supports soft off (power state S5), the function returns TRUE. Otherwise, the function returns FALSE.
Remarks
This information is also available through the CallNtPowerInformation function. The value is returned in the SystemS5 member of the SYSTEM_POWER_CAPABILITIES structure.
Starting with Windows Vista, computers must support the soft off power state. Therefore, this function is relevant only to Windows Server 2003 and earlier operating systems.
