Conversion from boost::shared_ptr to std::shared_ptr?

Question

I got a library that internally uses Boost\'s version of shared_ptr and exposes only those. For my application, I\'d like to use std::shared_ptr wh

You can carry the boost::shared_ptr "inside" the std::shared_ptr by using the destructor to carry the reference around:

template
void do_release(typename boost::shared_ptr const&, T*)
{
}

template
typename std::shared_ptr to_std(typename boost::shared_ptr const& p)
{
    return
        std::shared_ptr(
                p.get(),
                boost::bind(&do_release, p, _1));

}

The only real reason to do this is if you have a bunch of code that expects std::shared_ptr.
