boost disable_interruption不会阻止thread_interrupted

Question

我试图防止它在特定范围内的线程中断。但是，使用boost::this_thread::disable_interruption di()似乎没有任何效果。

#include <boost/thread.hpp> 
#include <iostream> 

void worker() { 
    std::cout << "START" << std::endl; 

    for(;;) { 
     { 
      boost::this_thread::disable_interruption di(); 
      try { 
       boost::this_thread::sleep(boost::posix_time::seconds(1)); 
      } 
      catch(boost::thread_interrupted & e) { 
       assert(false); 
      } 
     } 

     try { 
      boost::this_thread::interruption_point(); 
     } 
     catch(boost::thread_interrupted & e) { 
      break; 
     } 

    } 

    std::cout << "END" << std::endl; 
} 


int main() { 
    boost::thread thread(&worker); 
    thread.interrupt(); 
    thread.join(); 
} 

文档似乎暗示boost::this_thread::sleep()不会抛出boost::thread_interrupted而di在范围内。

我在做什么错？

你应该在下面的行删除括号：

//boost::this_thread::disable_interruption di(); 
boost::this_thread::disable_interruption di; 

而不是创造disable_interruption对象，你声明的函数迪。
