hi everyone,
I wrote a small program to access the inode data for a
given filename with it's path. I am not sure whether
what i wrote was correct , but i could'nt get it to
compile at all and am clueless abt the error that it
is giving me.
The program is :
----------
#include <linux/fs.h>
#include <asm/namei.h>
#include <linux/dcache.h>
#include <linux/fs.h>
#include <linux/mount.h>
#include <linux/vfs.h>
#include <linux/stat.h>
#include <linux/string.h>
#include <stdio.h>
#define LOOKUP_FOLLOW (1)
#define LOOKUP_POSITIVE (8)
int resolve(const char * filename)
{
struct nameidata nd;
struct dentry *dentry;
struct inode *inode;
int error;
if(path_init(filename,LOOKUP_FOLLOW|LOOKUP_POSITIVE,&nd))
error = path_walk(filename,&nd);
if(error || !(nd.dentry->d_inode))
printk("Problem with %s filename\n",filename);
else{
dentry = nd.dentry;
}
inode = dentry->d_inode;
fprintf(stderr,"ino no is : %u",inode->i_ino);
return 1;
}
int main(int argc, char *argv[])
{
const char *filename = "/sbin/init";
int result = resolve(filename);
return 1;
}
----------
The error that it generates is :
----------
# gcc inode_data.c
inode_data.c: In function `resolve':
inode_data.c:16: storage size of `nd' isn't known
inode_data.c:29: dereferencing pointer to incomplete
type
inode_data.c:31: dereferencing pointer to incomplete
type
#
----------
Please suggest me how to get rid of these errors ??
Thanks
karthik
