.SH "RETURN VALUE"

.PP 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**.

.PP 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.

.PP **udev\_device\_get\_udev()** always returns a valid pointer to the udev context that this device belongs to.

.PP 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.

.PP 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.
