如何获取当前线程的std :: thread? [英] How to get std::thread of current thread?

问题描述

如何获取表示当前(已运行线程)的std::thread对象.

How can I get a std::thread object representing current (already running thread).

我知道我可以做std::this_thread::get_id().但是，这会给我一个std::thread:id对象.

I know I can do std::this_thread::get_id(). However, this will give me a std::thread:id object.

我的主要目标是允许其他一些线程加入当前线程.但是，问题在于当前的代码不是通过创建std :: thread开始的，因此我无法事先保存它.

My main goal is to allow some other thread to join current one. However, the problem is that current one wasn't started by creation of std::thread, so I couldn't have saved it beforehand.

推荐答案

您无法获得std::thread对象，该对象引用的不是std::thread构造函数创建的线程.要么始终使用C ++线程库，要么根本不使用它.例如，如果当前线程是由pthread_create创建的，则需要使用pthread_join将其加入.

You can't get a std::thread object referring to a thread that wasn't created by the std::thread constructor. Either consistently use the C++ thread library, or don't use it at all. If the current thread was created by pthread_create, for example, it will need to be joined to using pthread_join.
