对于pthread的，如何从主线程杀子线程 [英] For pthread, How to kill child thread from the main thread

问题描述

我用pthread_create的创建多个子线程。而此时，主线程要杀死所有的子线程还是会有段falut。它的功能，我应该用它来完成呢？我搜索从谷歌的答案，得到了像pthread_kill功能。但我不知道哪一个信号，我应该发送给子线程要杀死他们。我的运行环境是RHEL 5.4和编程语言是C。

I use pthread_create to create several child threads. At a time, the main thread wants to kill all child threads or there will be segment falut. Which function should I use to finish that? I searched the answer from google and got function like pthread_kill. But I did not know which signal should I send to the child thread to kill them. My running environment is RHEL 5.4 and programming language is C.

推荐答案

It is possible to "cancel" a thread using pthread_cancel. However, this isn't typically best practice though under extreme circumstances like a SEGFAULT it may be conisdered a reasonable approach.
