How to Find Processlist Thread id in gdb !!!!!GDB 使用

https://mysqlentomologist.blogspot.jp/2017/07/ Saturday, July 29, 2017 How to Find Processlist Thread id in gdb I was involved in a discussion on some complex MySQL-related problem where we had to study backtraces of all threads in gdb (p…

线程标识符id可以通过thread::get_id()获得,若thread obejct没有和任何线程关联则返回一个NULL的std::thread::id表示没有任何线程.当前线程若想获得自己的id可以调用std::this_thread::get_id(). thread::id对象可以被任意复制和比较.这里的比较语义是:若相等表示是同一个线程或者都没有线程,不等表示不同的线程. bool operator== (thread::id lhs, thread::id rhs) noexcep…

根据 thread id 停止一个线程

std::thread中获取当前线程的系统id

std::thread不提供获取当前线程的系统id的方法,仅可以获取当前的线程id,但是我们可以通过建立索引表的方式来实现 std::mutex m; std::map<std::thread::id, pid_t> threads; void add_tid_mapping() { std::lock_guard<std::mutex> l(m); threads[std::this_thread::get_id()] = syscall(SYS_gettid); } void…

多线程爬坑之路-Thread和Runable源码解析

多线程:(百度百科借一波定义) 多线程(英语:multithreading),是指从软件或者硬件上实现多个线程并发执行的技术.具有多线程能力的计算机因有硬件支持而能够在同一时间执行多于一个线程,进而提升整体处理性能.具有这种能力的系统包括对称多处理机.多核心处理器以及芯片级多处理(Chip-level multithreading)或同时多线程(Simultaneous multithreading)处理器. 在一个程序中,这些独立运行的程序片段叫作"线程"(Thread),利用它编程…

Linux process vs thread

Linux process vs thread Question I have a query related to the implementation of threads in Linux. Linux does not have an explicit thread support. In userspace, we might use an thread library (like NPTL) for creating threads. Now if we use NPTL its s…
