当一个异常在多线程C ++ 11程序中未处理时会发生什么? [英] What happens when an exception goes unhandled in a multithreaded C++11 program?
问题描述
如果我有一个C ++ 11程序运行两个线程,其中一个抛出一个未处理的异常,会发生什么?整个程序会死亡吗?将异常抛出的线程单独死亡(如果是这样,我可以获得这种情况下的异常)?
If I have a C++11 program running two threads, and one of them throws an unhandled exception, what happens? Will the entire program die a fiery death? Will the thread where the exception is thrown die alone (and if so, can I obtain the exception in this case)? Something else entirely?
推荐答案
没有什么真的改变了。 n3290中的措辞是:
Nothing has really changed. The wording in n3290 is:
如果没有找到匹配的处理程序,函数
std :: terminate / code>被调用
If no matching handler is found, the function
std::terminate()
is called
terminate
的行为可以用 set_terminate
定制,但
The behavior of terminate
can be customized with set_terminate
, but:
Required behavior: A
terminate_handler
shall terminate execution of the program without returning to the caller.
