Windows C++如何调用从一个线程到另一个线程的阻塞读取？
我有两个 C++ 类（Windows、Visual Studio 2010），每个类运行不同的线程，我想以一种简单的方式在它们之间发送消息。这个想法是，main 调用 class2 上的读取，等待 class2 获取数据，然后主类接收它并继续 - 类似于套接字，但在同一程序的两个类/线程之间。这可以做到吗？
示例：
class MyClass(){
...
void run(){...}; //runs a thread here that collects data from a network socket
};
int main(){
MyClass *mc = new MyClass();
mc->run();
...
mc->receiveData(); //returns a value AFTER the class gets a hold of it, and blocks in the meantime...
}
有什么简单的方法可以做到这一点吗？有点像创建一个套接字并从中读取，直到它从网络接收到数据包/数据时它才会返回，除非我想要一个类在本地系统上执行此操作。谢谢！
I have two classes in C++ (Windows, Visual Studio 2010) each running a different thread, and I want to send messages between them in a simple way. The idea is that the main calls a read on class2, waits for class2 to get the data, and then main class receives it and continues - something like a socket, but between two class/thread on the same program. Can this be done?
Example:
class MyClass(){
...
void run(){...}; //runs a thread here that collects data from a network socket
};
int main(){
MyClass *mc = new MyClass();
mc->run();
...
mc->receiveData(); //returns a value AFTER the class gets a hold of it, and blocks in the meantime...
}
Is there any simple way to do this? Kind of like creating a socket, and reading from it, it won't return until it receives the packet/data from the network, except I want a class to do this on the local system. Thanks!

创建线程并在线程上调用 join()。 （谷歌那个）。线程连接将允许您生成一个线程进行处理，并指示一旦 main 到达连接，它应该等待它正在连接的线程完成。当线程在 join 语句处返回时，您可以从线程返回一个值，这样 main 就可以在需要时知道结果。
Create the thread and call a join() on the thread. (Google that). Thread joins will allow you to spawn off a thread for processing and indicate that once main reaches the join, it should wait for the thread it is joining to complete. You can return a value from the thread when it returns at the join statement so main can know the result if you need it.
听起来您想要一个线程安全的队列来放置消息。
查看 Microsoft 并行模式库中的“并行容器和对象” 。该页面有一个示例，展示了 concurrent_vector 的使用。
Sounds like you want a thread-safe queue to put your messages on.
Check out the 'Parallel containers and objects' in the Microsoft Parallel Patterns Library. That page has an example showing the use of
concurrent_vector.
