C+＋并发类成员函数调用（练习1）

一般类成员函数开线程格式 std::thread t1(&类名::函数，&实例化对象，参数....) ||std::thread t1(std::bind(&&类名::函数，&实例化对象，参数....))

 #include <iostream>
 #include <mutex>
 #include <thread>
 #include <vector>
 #include <string>
 #include <condition_variable>
 #include <future>

 template<typename T>
 class vector_safe
 {
 public:
     vector_safe():ready(false),proccess(false){}
 public:
     void push(T& value)
     {
         std::unique_lock<std::mutex> m_guard(mut);
         vec.push_back(value);
         ready=true;
         m_guard.unlock();
         condit_va.notify_one();
     }
     void get_and_pop(T& value)
     {
         std::unique_lock<std::mutex> m_guard(mut);
         condit_va.wait(m_guard,[this](){return ready;});//wait-------线程完毕数据；

         value=vec.front();
         vec.pop_back();
         proccess=true;
          m_guard.unlock();

     }
 private:
     std::vector<T> vec;
     std::mutex mut;
     std::condition_variable condit_va;
     bool ready;
     bool proccess;

 };
 vector_safe<std::string> obj;

 int main()
 {

         std::string str1("this is dream");
         std::string str2("没覆盖?");
     std::thread t1(std::bind(&vector_safe<std::string>::push,&obj,std::ref(str1)));
     std::thread t2(std::bind(&vector_safe<std::string>::get_and_pop,&obj,std::ref(str2)));
         t1.join();
         t2.join();
         std::cout<<str2<<std::endl;
         return ;
 }

运行结果：
xcode 7.2
this is dream
Program ended with exit code:
