[Boost-users] [shared_ptr] Is there an interface to set the ptr a shared_ptr holds

Hello,

I have the following code scenario:

A *pa = NULL;

// pa will be allocated here (by 3rd-party function)
// by setA(),
// whose behavior could not be changed
setA(pa);   // prototype: void setA(A*& pa)

//...

pa->close();


I want to apply shared_ptr to make it easier to maintain,
or, more specifically here, to save a close() call.

new version:

boost::shared_ptr<A> pa(NULL, boost::bind(&A::close, _1));
setA(pa.get());  // because get() returns T* instead of T*&, 
                 // this line chokes the compiler

//pa->close();    not needed any more

Is there any way to get my goal accomplished?

Thanks for any help.

B/Rgds

Max
