本文介绍了POSIX系统上的僵尸线程的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
僵尸线程如何在C/C ++中形成，并且您需要确保做什么以防止它们被创建?我知道它们只是无法正常终止的普通线程，但是我对具体细节有些困惑.
How do zombie threads get formed in C/C++, and what do you need to make sure to do in order to prevent them from being created? I know they're just normal threads that didn't terminate properly, but I'm a little hazy on the specifics.
推荐答案
僵尸线程是可连接的线程，该线程已经终止，但是 还没有加入.通常，任何一个线程都应该在某个位置连接 时间，否则应该分开.否则，操作系统将保持其状态 以便将来可能需要加入，这会占用资源.
A zombie thread is a joinable thread which has terminated, but which hasn't been joined. Normally, either a thread should be joined at some time, or it should be detached. Otherwise, the OS maintains its state for some possible future join, which takes resources.
