NAME

       udev_list_entry, udev_list_entry_get_next, udev_list_entry_get_by_name,
       udev_list_entry_get_name, udev_list_entry_get_value - Iterate and access udev lists

SYNOPSIS

       #include <libudev.h>

       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 *name);

       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);

RETURN VALUE

       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.

HISTORY

       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.
