Yes, for the time being..it has on 5 elements. They
are int type at this

You can use ioctl command to communicate with your
driver.
User-space (application):
int ioctl(int fd, int cmd, ...);
Kernel-space (driver):
int (*ioctl) (struct inode *inode, struct file *filp,
unsigned int cmd, unsigned long arg);
Since you want to get only one value, you can use:
__put_user(datum, ptr)

You might also want to check the scull example from
