竟然struct file的竟然没有成员

不知道为什么，编译器没有通过，说file没有这个结构

也许是编译器的原因吧，到网上有关这个结构体的资料也蛮少的。

不过这个结构体本身占用了32个字节。

 

 

#include<stdio.h>
#include<stdlib.h>

int displayfileinfo(FILE * fp)
{
/*
if(fp==NULL){printf("Cannot open file/n");exit(1);}
printf("The file in memorybuffer level is %d/n",&fp->level); 
printf("The file status flags is %d/n",&fp->flags);
printf("The file discription is %c/n",&fp->fd); 
printf("The file in memory buffer size is %d/n",&fp->bsize);
printf("The file in memory buffer address is %d/n",fp->buffer); 
*/
/*
if(fp==NULL){printf("Cannot open file/n");exit(1);}
printf("The file in memorybuffer cleft is %d/n",fp->cleft); 
printf("The file next char is %c/n",fp->nextc);
printf("The file discription is %d/n",fp->fd); 
//printf("The file in memory buffer size is %d/n",&fp->bsize);
printf("The file in memory buffer address is %c/n",fp->buff);
 */  
}

int main(void)
{
FILE *fp,fp1;
fp=fopen("test.txt","r+");
if(fp==NULL){printf("Cannot open file/n");exit(1);}   
//displayfileinfo(fp); 
 printf("The file struct size is %d/n",sizeof(fp1));
 while(1){};
   
}
