On success, **udev_device_get_syspath()**, **udev_device_get_sysname()**,
**udev_device_get_sysnum()**, **udev_device_get_devpath()**,
**udev_device_get_devnode()**, **udev_device_get_devtype()**,
**udev_device_get_subsystem()**, **udev_device_get_driver()** and
**udev_device_get_action()** return a pointer to a constant string
that describes the requested property. The lifetime of this string
is bound to the device it was requested on. On failure, each
function may return **NULL**.
On success, **udev_device_get_devnum()** returns the device type of
the passed device. On failure, a device type with minor and major
number set to **0** is returned.
**udev_device_get_udev()** always returns a valid pointer to the udev
context that this device belongs to.
On success, **udev_device_get_parent()** and
**udev_device_get_parent_with_subsystem_devtype()** return a pointer
to the parent device. No additional reference to this device is
acquired, but the child device owns a reference to such a parent
device. On failure, **NULL** is returned.
On success, **udev_device_get_is_initialized()** returns either **1** or
**0**, depending on whether the passed device has already been
initialized by udev or not. On failure, a negative error code is
returned. Note that devices for which no udev rules are defined
are never reported initialized.HISTORY top
