I'm trying to find a production quality lock free reference counted pointer implementation and boost::shared_ptr seems promising. However boost::atomic_is_lock_free(shared_ptr) returns false on Windows. I'm going to try on SUSE linux soon.
According to http://www.boost.org/doc/libs/1_43_0/libs/smart_ptr/shared_ptr.htm,
Starting with Boost release 1.33.0, shared_ptr uses a lock-free implementation on the following platforms:
GNU GCC on x86 or x86-64;
GNU GCC on IA64;
Metrowerks CodeWarrior on PowerPC;
GNU GCC on PowerPC;
Windows. Then why does boost::atomic_is_lock_free(shared_ptr) returns false?
atomic_is_lock_free indicates whether atomic operations on the shared_ptr object are lock-free. The reference count is lock free. In Christ, Steven Watanabe
