In man 3 rtnetlink, the example code includes the lines:
rta = (struct rtattr *)(((char *) &req) +
NLMSG_ALIGN(n->nlmsg_len));
in which the variable "n" is nowhere declared. It seems likely that
NLMSG_ALIGN(req.nh.nlmsg_len) was intended, albeit I am so deeply
ignorant of relevant systems that I am learning about them by reading
man pages, so I may easilly be wrong ...
I am also acutely aware of the bug already noted on the man page, but
you clearly already know about that one !
