{function SetSuspendState(
Hibernate: Boolean,
ForceCritical: Boolean,
DisableWakeEvent: Boolean);
{ Parameters:
Hibernate: If this parameter is TRUE, the system hibernates.
If the parameter is FALSE, the system is suspended.
ForceCritical: If this parameter is TRUE, the system suspends operation immediately;
if it is FALSE, the system broadcasts a PBT_APMQUERYSUSPEND event to
each application to request permission to suspend operation.
DisableWakeEvent: If this parameter is TRUE, the system disables all wake events.
If the parameter is FALSE, any system wake events remain enabled.
Windows NT/2000/XP: Included in Windows 2000 and later.
Windows 95/98/Me: Included in Windows 98 and later.}
