当在动态库执行时,这个a对象的初始化是在动态库入口点(DllMain entry point),也就是DllMain函数中完成的。 std::thread的构造函数中创建新线程,在新线程开始执行线程过程之前不能返回。创建新线程时,在开始执行线程过程之前,会以DLL_THREAD_ATTACH方式调用动态库 的入口点(DllMain)1。为此,新线程必须获取加载程序锁。

上一篇《C++11 并发指南二(std::thread 详解)》中主要讲到了 std::thread 的一些用法,并给出了两个小例子,本文将介绍 std::mutex 的用法。 Mutex 又称互斥量,C++ 11中与 Mutex 相关的类(包括锁类型)和函数都声明在 <mutex> 头文件中,所以如果你需要使用 std::mutex,就必须包含 <mutex> 头文件。
例如: struct example{ int k, m, n; } object = {.m = 10, .n = 200}; 注意:该方法只能用在定义时初始化,不能再后续使用 printf()和scanf()函数系列的增强 C99中printf()和scanf()函数系列引进了处理long long int和unsigned long long int数据类型的特性。long long int 类型的格式修饰符...
