struct udev_list_entry
*udev_list_entry_get_next(struct udev_list_entry *list_entry);
struct udev_list_entry
*udev_list_entry_get_by_name(struct udev_list_entry *list_entry,

const char
*udev_list_entry_get_name(struct udev_list_entry *list_entry);
const char
*udev_list_entry_get_value(struct udev_list_entry *list_entry);
On success, udev_list_entry_get_next() and
udev_list_entry_get_by_name() return a pointer to the requested
list entry. If no such entry can be found, or on failure, NULL is
returned.
On success, udev_list_entry_get_name() and
udev_list_entry_get_value() return a pointer to a constant string
representing the requested value. The string is bound to the
lifetime of the list entry itself. On failure, NULL is returned.
udev_list_entry_get_next(), udev_list_entry_get_by_name(),
udev_list_entry_get_name(), and udev_list_entry_get_value() were
added in version 221.
