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

I have the following code scenario:

A *pa = NULL;

//...

pa->close();

I think the following is fine: A *pa_ = 0; setA(pa_); boost::shared_ptr<A> pa(pa_, boost::bind(&A::close, _1)); Since the shared_ptr constructor will call the deleter if its internal allocation fails. ~ Scott
