特别是,我正在寻找一个阻塞队列.在C 11中有这样的事吗?如果没有,我的其他选择是什么?我真的不想再去自己的线程了.方式太容易出错.
解决方法:
According to Diego Dagum from Microsoft’s Visual C++ Team:
A recurrent question (well, one of the many) is about STL containers
and whether they are thread safe.Taking Stephan’s words here, the reality is that they aren’t, not as a
bug but as a feature: having every member function of every STL
container acquiring an internal lock would annihilate performance. As
a general purpose, highly reusable library, it wouldn’t actually
provide correctness either: the correct level to place locks is
determined by what the program is doing. In that sense, individual
member functions don’t tend to be such correct level.
The Parallel Patterns Library(PPL)包括几个容器,它们提供对其元素的线程安全访问:
> concurrent_vector Class是一个序列容器类,允许随机访问任何元素.它支持并发安全追加,元素访问,迭代器访问和迭代器遍历操作.
> concurrent_queue Class是一个序列容器类,允许以先进先出的方式访问其元素.它支持一组有限的并发安全操作,例如push和try_pop,仅举几例.
一些样品here.
