C ++标准 3.6.3 表示
静态持续时间的初始化对象的析构函数main
在Windows上，您可以使用 FreeLibrary 和linux dlclose 以卸载动态链接库。你可以在从main返回之前调用这些函数。
卸载共享库的副作用是运行库中定义的静态对象的所有析构函数。
这是否意味着它违反了C ++标准，因为这些析构函数已经过早运行？解决方案
如果你非常努力这样做，它们只会过早运行 - 默认行为是标准符合。
The C++ standard 3.6.3 states
Destructors for initialized objects of static duration are called as a result of returning from main and as a result of calling exit
On windows you have FreeLibrary and linux you have dlclose to unload a dynamically linked library. And you can call these functions before returning from main.
A side effect of unloading a shared library is that all destructors for static objects defined in the library are run.
Does this mean it violates the C++ standard as these destructors have been run prematurely ?
They are only run prematurely if you go to great effort to do so - the default behavior is standard conforming.
