For example, to declare a function named begin () as a constructor, and end () as a destructor, you need to tell gcc about these functions through the following declaration. 1 2 void begin (void) __attribute__((constructor)); void end (void) __attribute__((destructor)); An alterna...
You may provide an optional integer priority to control the order in which constructor and destructor functions are run. A constructor with a smaller priority number runs before a constructor with a larger priority number; the opposite relationship holds for destructors. So, if you have a construct...
这个错误的意思是在定义函数 invfun() 前面缺少了函数的返回类型。在 C 语言中，函数的定义必须包含函数的返回类型，例如 int、float 等。下面是修改后的代码：include <stdio.h> define MAX 200 void invfun(int[],int); // 函数声明 int main() // main() 函数必须有返回值 { int a[...
