hello list,
can someone suggest the way to find the file size in ext2fs ? actually, want to find the file size in bytes,i.e, the true file size and not in terms of the blocks allocated to the file.
is there any EOF char in ext2fs files ? if yes. what is it ? is there any other way of knowing the file size than to count up to EOF ???
thanx,
Shalini

In the kernel:
inode->i_size
In a regular application ( in C ):
#include <sys/stat.h>
#include <unistd.h>
off_t getfilesize(char *myfile)
{
struct stat fileinfo;
int err;
err = stat(myfile, &fileinfo);
if(err == -1) {
/* Do something about the error */
return 0;
}
return fileinfo.st_size;
}

No.
The file size is kept in filesystem metadata, not in the file.
(Every sane filesystem handles file size this way. Even HFS/HFS+)
