Hi all,

Supposing i create a file of size 10K, it will occupy 2 blocks (4K each).

I must be missing something obvious. Why does a file of 10K only needs 2 blocks of 4K ? You haven't mentioned that it has any holes in it.

Now if i want to read only 1 block from it how can i do it?

read(fd, buf, 4096) ; would this mean i would read the first block and all its contents?

Thanks
