RETURN VALUE
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.
