Linux C 模拟 constructor and destructor

Linux 复制粘贴 分为 缓冲区 和 系统剪贴板

1.缓冲区只能在本编辑内有效
2.系统剪贴板可以粘贴到外部


cat "content" | xclip -selection c 
复制到系统剪贴板，可以粘贴到外部！


设置段
.ctors
构造函数?
.dtors
析构函数?

#include
void my_init_0(){
	printf("init 0 OKn");
}
void my_init_1(){
	printf("init 1 OKn");
}
typedef void (*ctor_t)();


__attribute__((section(".ctors"))) 
ctor_t my_init_0_c = my_init_0;

__attribute__((section(".ctors"))) 
ctor_t my_init_1_c = my_init_1;



int main(){
	printf("main OKn");
	return 0;
}

void my_destroy_0(){
	printf("destroy 0 OKn");
}
void my_destroy_1(){
	printf("destroy 1 OKn");
}
typedef void (*dtor_t)();
