The SetSystemPowerState function suspends the system by shutting power down. Depending on the ForceFlag parameter, the function either suspends operation immediately or requests permission from all applications and device drivers before doing so.
BOOL SetSystemPowerState(
BOOL fSuspend, | |
BOOL fForce | |
); |
If power has been suspended and subsequently restored, the return value is nonzero.
If the system was not suspended, the return value is zero. To get extended error information, call GetLastError.
If any application or driver denies permission to suspend operation, the function sends a PBT_APMQUERYSUSPENDFAILED message to each application and driver. If power is suspended, this function returns only after system operation is resumed and related WM_POWERBROADCAST messages have been sent to all applications and drivers.
PBT_APMQUERYSUSPEND, PBT_APMQUERYSUSPENDFAILED, PBT_APMSUSPEND, WM_POWERBROADCAST
