我有一个“大”问题。我目前正在尝试在 Linux 上的程序(它是一个虚拟机)中获取我的 dtor 列表的地址。显然有一个析构函数,但是当我使用 nm 并显示所有地址及其名称时,我找不到它;唯一与之相关的是do_global_dtors_aux。此外,当代码运行时,它按预期工作得非常好。这是我的一段代码:
#include <stdlib.h>
#include <stdio.h>
static void cleanup(void) __attribute__ ((destructor));
int main() {
printf("in the main function...");
exit(0);
}
void cleanup(void){
printf("in the cleanup");
}
这是我使用的时候nm
