MSVC的C和C库在main之前和之后都做了很多魔术.此外,您正在使用启用各种运行时检查的开关进行编译(这需要例如_RTC *符号).您还有用于处理的导入,例如堆和调试构建错误报告机制.
“编译器魔术”术语中的“魔术”(编译器/工具链在幕后为您做的事情)包括例如: >设置堆栈“cookies”以检测堆栈溢出 如果你在调试模式下构建这个应用程序,并在main的开头设置一个断点,你会看到什么叫main.通读,例如__tmainCRTStartup及其调用的函数. (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
