Web通过Strand执行的函数不需要显式地同步，这简化了异步代码的编写。 在程序中，如果你只有一个IO线程(比如在Boost::Asio中，只有一个线程调用了 io_service::run )，那么你并不需要同步。这种情况下该线程中所有的函数会依次执行。 WebThe constructor of boost::scoped_thread expects an object of type boost::thread.In the destructor of boost::scoped_thread an action has access to that object. By default, boost::scoped_thread uses an action that calls join() on the thread. Thus, Example 44.2 works like Example 44.1. You can pass a user-defined action as a template parameter. …
