数据结构自己写的linux链表的实现

#include<stdio.h>
#define	OFFSET(type,member) (int)(&(((type *)0)->member));
typedef struct _data{
	int a;
	int b;
	int c;	
}Data;
int main (int argc ,char **argv)
{
	int offset;
	Data p;
//	p= 0x00;
//	temp=(int)(&(p->c));
	//offset = (int)(temp) -(int)p;
//	offset = (int)(&(((Data *)0)->c));
	offset=OFFSET(Data,c)
	printf("offset: %d\n",offset);
	
}
