I don't know offhand if you get to see if suspend or hibernate is enabled. 
It seems that all or at least most of the time it is already suspended 
before entering hibernate.

Look at the power management API, where a WM_POWERBROADCAST message is sent.

The only functions I know of are CallNtPowerInformation() and
IsPwrHibernateAllowed():

You can't enable/disable hibernation.  What you can do, however, is
intercept the WM_POWERBROADCAST message.  Check for the
PBT_APMQUERYSUSPEND event, and return BROADCAST_QUERY_DENY in
response.

Something else to keep in mind - starting with Windows Vista, you
can't block power management operations anymore.  So you may want to
re-think why you are trying to disable hibernation in the first place.
