Syntax of atexit() function: C++11: extern "C" int atexit (void (*func)(void)) noexcept; extern "C++" int atexit (void (*func)(void)) noexcept; Parameter(s) func– represents the function to be called at program
In the C Programming Language, the atexit function registers a function as a termination function which is called if the program terminates normally.When calling the atexit function more than once, the last function to be registered is the first function that will be called when the program is ...
This program pushes four functions onto the stack of functions to be executed whenatexitis called. When the program exits, these programs are executed on a last in, first out basis. C // crt_atexit.c#include<stdlib.h>#include<stdio.h>voidfn1(void),fn2(void),fn3(void),fn4(void);int...
[gong@Gong-Computer APUE]$ ./atexit In main in func1 in func2 in func3 根据exit 的执行过此可知,exit 首先会调用各个终 止处理程序,然后按需多次调用 fclose(),关闭所有打 开流,也就是说 exit 函数会执行一个标准 I/O 库的清理 关闭操作:对所有打开的流调用 fclose(),这样就会造 成所有缓冲的输出...

针对你提供的错误信息“exception ignored in atexit callback: <function _openpyxl_shutdown at 0x0000>”,这里有几个可能的解决步骤: 检查openpyxl库的版本: 确保你安装的openpyxl库是最新的,或者至少是一个稳定的版本。有时候,库的旧版本可能包含未修复的bug。 查看openpyxl的源代码: 错误信息中提到的_openpyxl_...
gram's main(). Functions so registered arecalled in the reverse order of their registration;no arguments are passed. 调用时注册的反向调用。C++的析构函数和构造函数就是与这个类似,估计C++多少受到这个影响。 The same function may be registered multiple times: it is called once ...

Functions thus registered are automatically executed upon normal interpreter termination.atexitruns these functions in thereverseorder in which they were registered; if you registerA,B, andC, at interpreter termination time they will be run in the orderC,B,...
