26 @post This function will return after posting an event in system event queue. The processing of this event might |
|
27 take some time and even might be cancelled if the system cannot be restarted safely. The execution of the calling |
|
28 thread will continue for an indefinte period of time after this call, but it has no guarantees to finish execution. |
|
29 It is strongly advised to delay for a sufficient period of time to let the shutdown request be processed. |
