SetSuspendState function (powrprof.h)
Suspends the system by shutting power down. Depending on the Hibernate parameter, the system either enters a suspend (sleep) state or hibernation (S4).
Syntax
BOOLEAN SetSuspendState(
[in] BOOLEAN bHibernate,
[in] BOOLEAN bForce,
[in] BOOLEAN bWakeupEventsDisabled
);
Parameters
[in] bHibernate
If this parameter is TRUE, the system hibernates. If the parameter is FALSE, the system is suspended.
[in] bForce
This parameter has no effect.
[in] bWakeupEventsDisabled
If this parameter is TRUE, the system disables all wake events. If the parameter is FALSE, any system wake events remain enabled.
Return value
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Remarks
The calling process must have the SE_SHUTDOWN_NAME privilege. To enable the SE_SHUTDOWN_NAME privilege, use the AdjustTokenPrivileges function. For more information, see Changing Privileges in a Token.
An application may use SetSuspendState to transition the system from the working state to the standby (sleep), or optionally, hibernate (S4) state. This function is similar to the SetSystemPowerState function.
For more information on using PowrProf.h, see Power Schemes. For information about events that can wake the system, see System Wake-up Events.
