Read/Write operations

Yops,

        In struct file_operations read and write are define as follow
        ssize_t (*read) (struct file *fops, char *buf, size_t count, loff_t
*ppos);
        ssize_t (*write) (struct file *fops, const char *buf, size_t count,
loff_t *ppos);

        Just a little question, in which case the value of *ppos is different
of fops->f_pos.

        Thanks.
