In the manual page is written that "RTM_F_NOTIFY if the route changes, notify the user via rtnetlink". Can you give me some information about how this 'notifying' works? How can I be notified? Will I be notified about one certain route change or only generaly about that route table changed?
I was looking for in the source of net-tools 1.60 and libnl and on google, but without success. Can you give me some link or info?
Any help appreciated!
