我可以在C ++中阻止线程及其子级吗？>

Question

我有这样的代码

Create thread_1 and bind task 1 to that;
Create thread_2 and bind task 2 to that;
Create thread_3 and it monitors the keyboards and work as follow:
     while(true){
       get the next key;
       if (the next key == 'p')
            pause_the_code();
       if (the next key == 'r')
            resume_the_code();
       if(the next key == 'q'
            exit the while loop
      }
// can I here block the Thread_1 and _Thread_2 with all of their children 
//with wait() when I call pause_the_code(); or notify them when I call resume_the_code();
请注意，hread_1和Thread_2可以动态创建不同的线程。

我有这样的代码创建线程_1并将任务1绑定到该代码；创建thread_2并将任务2绑定到该线程；创建thread_3并监视键盘并按以下方式工作：while（true）{...

否，您无法从一个线程伸出手来暂停或阻止另一个线程。并非以任何安全的方式。
