if (joining != NULL) restart(joining); /* If this is the initial thread, block until all threads have terminated. If another thread calls exit, we'll be terminated from our signal handler. */ // 如果是主线程退出,通知manage线程,如果是一般线程则直接执行exit退出 if (self == __pthread_m...
join会阻塞当前线程，直到调用join的线程完成其执行。

本文翻译自C++11 Multithreading – Part 2: Joining and Detaching Threads,转载自C++11多线程-【2】线程的join和detach 本文介绍线程对象 std::thread 的 joining 和 detaching。 使用std::thread::join() 进行线程的 joining 一旦一个线程开始之后,另一个线程可以等待此线程结束。

thread是C++11中提供多线程编程的模块,使用的时候需要包含<thread>头文件。 首先我们先来看一下简单的hello world的多线程的代码(win10下vs2019) 这个创建的方式就是以函数作为一个入口,创建了一个子线程,那么创建的语句就是第11行代码所示,所传入的参数就是入口的函数名。在创建了这个子线程之后,这个子线程就开...
想请教一下什么情况下调用pthread_join会导致free的错误呢,在写线程池回收时遇到的问题,回收的线程id也能正常打印出来 LDTP 毛蛋 1 一共12个线程,每次都正好是回收第4个线程时就异常了 LDTP 毛蛋 1 GTA小鸡 吧主 14 那说明pool->threads[index]不是一个有效的pthread_t对象。 LDTP 毛蛋 1 破案了,分配...
A discussion is the cornerstone of an online community. It’s where ideas are exchanged, opinions offered, and arguments debated. Discussions are generally free form and can cover a wide range of topics. They might be lengthy and include lots of participants or be confined to just a few post...
Weavers ___ threads to make cloth. A. combine B. join C. connect D. unite 相关知识点: 试题来源: 解析 B。本题考查动词辨析。“join”有“连接、结合”之意,在这里指织工把线连接起来做成布,符合语境。“combine”强调混合、结合多种事物;“connect”侧重于连接两个不同的事物,但没有“join”那么...
