std::at_quick_exit

性病：：[医]速战速决[医]出口

Defined in header ​​
int at_quick_exit( /*atexit-handler*/* func int at_quick_exit( /*c-atexit-handler*/* func (1)(since C++11)
extern "C++" using /*atexit-handler*/ = void( // exposition-only extern "C" using /*c-atexit-handler*/ = void( // exposition-only(2)​

注册所指向的函数。func在快速程序终止%28via时被调用std::quick_exit29%。

从多个线程调用函数并不会引发数据竞争。实施应至少支持登记32职能。

将不调用已注册的函数。正常程序终止如果在这种情况下需要调用函数，std::atexit一定要用。

参数

func-pointer to a function to be called on quick program termination

返回值

​0​如果注册成功，则为非零值。

例外

noexcept规格：

noexcept

注记

这两个重载是不同的，因为参数的类型。func分别为%28语言链接是其类型%29的一部分。

例

另见

atexitregisters a function to be called on std::exit() invocation (function)
