I'd like to use a spsc_queue of unique_ptr's to bigger objects, to transfer ownership between threads. That way, I can create/allocate an object in a non-realtime thread, then transfer ownership to a realtime thread using a lockfree queue, and, using another queue, pass on the unique_ptr to another thread that takes care of cleanup when the realtime thread no longer needs the it. For example: boost::lockfree::spsc_queue > cb; Unfortunately, spsc_queue does not use move semantics (methods to push onto the queue take parameters as const reference and construct a copy in the queues internal storage), so i can not cb.push() a unique_ptr<string> onto my queue. Is it reasonable to want to add this, and if so, what would be the best place to submit a request? (I managed to get a simple example working by adding rvalue reference overrides of the queue's push() methods, and using std::move in the pop() method) bool push(T && t) { }; Also, I noticed that the destructor for the spsc_queue (with size fixed at compile-time) does not run destructors for it's contents. What could be the reason for this? Thomas
