hello,
    i found that in struct proc_dir_entry struct
file_operations *proc_fops; is defined. and struct
file_operations has defined  read, write,
poll,llseek,ioctl,flush,release,lock etc functions. so
can all these functions be used on any /proc entry in
usermode as well as in kenrel mode?
   Also can following functions be used on my own
created /proc file kernel module and when to use them
as i have alredy struct file_opereations read and
write routine that read/write to/from /proc file.
typedef int (read_proc_t)(char *page, char **start,
off_t off,
                          int count, int *eof, void
*data);
typedef int (write_proc_t)(struct file *file, const
char *buffer,
                           unsigned long count, void
*data);
typedef int (get_info_t)(char *, char **, off_t, int);

regards,
cranium.
