Please look at the current smart pointer locking method: http://code.axter.com/smart_ptr.h By using intrusive lock logic, you can lock the pointee, and thereby locking all the shared_ptr objects. Here's the smart pointer destructor: inline ~smart_ptr() throw() { m_ownership_policy.destructor_lock_policy(m_type); CHECKING_POLICY::before_release(m_type); m_ownership_policy.release(m_type, m_clone_fct, m_ownership_policy); CHECKING_POLICY::after_release(m_type); }
There's similar logic in constructor and assignment operator. This should work on all three main types of reference policies, to include reference-link.
That's what I thought. But if you have support from the pointee, why not just use intrusive_ptr? It should be even faster, on all operations, not just init.
