* Return:

*
|
|

* ENOMEM There is no memory for allocated space for var.

* EFAULT The pointer 'target' does not pass in corretly.

* ENOENT The pointer 'target' pointed to a wrong location.

* EPERM The pointer 'target' does not point to a mount inode.

* EINVAL The pointer 'label' does not pass in correctly.
