pthread 线程状态 [英] pthread thread state

问题描述

是否有一种机制可以用来判断 pthread 线程当前是否正在运行或已退出?如果线程尚未退出，pthread_join() 是否有方法可以在特定时间段后超时?

Is there a mechanism that I can use to tell if a pthread thread is currently running, or has exited? Is there a method for pthread_join() that is able to timeout after a specific period of time if the thread has not yet exited?

推荐答案

我刚刚将线程包装在 C++ 类中，并保留了一个状态变量，以便稍后检查.

I just ended up wrapping the thread in a C++ class and keeping a state variable around that could be checked later.
