The contents of the FILE struct are implementaton defined. Meaning they can change any time the C maintainers or OS developers need to do that.
This is Solaris 9's idea of a FILE struct. I would dig thru you /usr/include file tree and find what your version looks like. Plus, consider chacking the internal file pointer and other struct members after you have done just a single read operation - like fgets. If you wait until EOF, you get NULL pointers.
Hi all
Is it possible to copy a structure of a directory only.

GETS(3) Linux Programmer's Manual GETS(3)NAME
fgetc, fgets, getc, getchar, gets, ungetc - input of characters and strings
SYNOPSIS
#include <stdio.h>
int fgetc(FILE *stream);
char *fgets(char *s, int size, FILE *stream);
int getc(FILE *stream);
int getchar(void);
char *gets(char *s);
int ungetc(int c, FILE *stream);
DESCRIPTION
fgetc() reads the next character from stream and returns it as an unsigned char cast to an int, or EOF on end of file or error.
getc() is equivalent to fgetc() except that it may be implemented as a macro which evaluates stream more than once.
getchar() is equivalent to getc(stdin).
gets() reads a line from stdin into the buffer pointed to by s until either a terminating newline or EOF, which it replaces with '
