本篇博客讲述如何在多个线程之间共享数据，并且在各种情况下使用互斥量来防止线程之间对数据竞争访问。 互斥量 互斥量的使用很简单，所见即所得： 123std::mutex some_mutex;some_mutex.lock();some_mutex.unlock(); 但是通过这样的方法使用互斥量有点麻烦，因为这意味着需要在函数的每个出口，包括异常处理中调用 unlock()。一个更加 RAII

本篇博客简单复习一下，线程之间的锁机制，主要包括自旋锁、互斥锁、条件变量、读写锁。 自旋锁 自旋锁用于保护临界区，其原理就是反复地进行 Test and Set 的忙等待。这种方法会一直占用CPU资源，不让出时间片，导致其他线程无法执行。但是，在临界区代码执行时间短的情况下，自旋锁可以避免线程的上下文切换。 1234567891011121314151617181920#include <
