Re: What do you all say of the file size ???

man fstat

              struct stat
              {
                  dev_t         st_dev;      /* device */
                  ino_t         st_ino;      /* inode */
                  mode_t        st_mode;     /* protection */
                  nlink_t       st_nlink;    /* number of hard links */
                  uid_t         st_uid;      /* user ID of owner */
                  gid_t         st_gid;      /* group ID of owner */
                  dev_t         st_rdev;     /* device type (if inode
device) */
                  off_t         st_size;     /* total size, in bytes */
                  unsigned long st_blksize;  /* blocksize for
filesystem I/O */
                  unsigned long st_blocks;   /* number of blocks
allocated */
                  time_t        st_atime;    /* time of last access */
                  time_t        st_mtime;    /* time of last
modification */
                  time_t        st_ctime;    /* time of last change */
              };

In particular, element st_size.

There is no EOF character stored in the file, that went out of style
with CP/M.  Although DOS/WinXX still support EOF characters, that
doesn't change the validity of my assertion.

If you are trying to find the file size of a raw disk partition that
has been formatted ext2 without using the linux file system resources
(i.e. fstat()), that is a pretty significant undertaking and you will
just have read and understand the ext2 sources.  You are not likely to
get much help or sympathy from this list.

hello list,

can someone suggest the way to find the file size in ext2fs ?(provided
the no. of blocks are known)

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 ???


if possible, please reply in a bit detail.
thanx,
Shalini
