Hi Friends,

I saw that this works well. I can destroy this object during the exit
of my program. I am interested in knowing that are will there be any
issues related to run time libraries, platform specific etc?

Well, I'm not a professional programmer but I would go global, and to
make it easy I would write a function to access the class using
extern. [Save time remembering class name]
extern Object *point_to_object;
static Object *GetObject()
{
return point_to_object;
}
As for thread safety I would just put the CS(critical section) code in
your global "point_to_object" class.
Note: I would also make your CS code a macro so if you have to change
it in the future.
Have a nice day.
