which type of smart pointer to use?

19 Mar 2007

      Hello,

When I reset the main pointer to an object, I want all other pointers 
pointing to that object to be reset as well. Which type of smart pointer 
should I use?

Example:

 boost::shared_ptr<MySillyClass> mySharedPtr1(new MySillyClass("test"));
 boost::shared_ptr<MySillyClass> mySharedPtr2 = mySharedPtr1;

 mySharedPtr1.reset();
 if(mySharedPtr2.use_count() > 0)
 {
  TRACE("still used\n");
 }
 else
 {
  TRACE("not used anymore\n");
 }

I am getting message "still used". I understand that is the normal behavior 
of boost::shared_ptr. Is there a smart pointer type that would print the 
second message?

Reason:
When I am done with an object, I would reset the main pointer to it and do 
not want other references to that object to be able to do anything with it.

Thanks for advice!
