SYNOPSIS#include <libudev​.h>const char *udev_device_get_syspath(struct udev_device *udev_device); const char *udev_device_get_sysname(struct udev_device *udev_device); const char *udev_device_get_sysnum(struct udev_device *udev_device); const char *udev_device_get_devpath(struct udev_device *udev_device); const char *udev_device_get_devnode(struct udev_device *udev_device); dev_t udev_device_get_devnum(struct udev_device *udev_device); const char *udev_device_get_devtype(struct udev_device *udev_device); const char *udev_device_get_subsystem(struct udev_device *udev_device); const char *udev_device_get_driver(struct udev_device *udev_device); struct udev *udev_device_get_udev(struct udev_device *udev_device); struct udev_device *udev_device_get_parent(struct udev_device *udev_device); struct udev_device *udev_device_get_parent_with_subsystem_devtype(struct udev_device *udev_device, const char *subsystem, const char *devtype); int udev_device_get_is_initialized(struct udev_device *udev_device); const char *udev_device_get_action(struct udev_device *udev_device);

RETURN VALUEOn 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​.
