Re: [Boost-users] initialization of boost::thread::id object

Boost lzw writes:

Thanks a lot for the answer. In fact, I am trying to associate data (std::vector<int> and Widget objects) with a boost::mutex by wrapping its interface [ lock(), try_lock() and unlock() ] as follows:   class Widget { ... }; // data to be associated with   class MyData { public:    MyData(std::vector<int>& v) : v_(v), w_(new Widget) { }

   ~MyData() {         m_.~mutex();

Do not call destructors manually. This will lead to undefined behaviour.

      delete w_;  }

 void unlock() {        id_ = 0;  // reset it, does not compile

id_ = boost::thread::id();

       m_.unlock();   }
