I am a bit confused with respect to the structure of rtnetlink requests.
It seems that in some circumstances a request can look like:
struct request
{
struct nlmsghdr header;
struct rtgenmsg body;
};
and in other cases it can look like:
struct request
{
struct nlmsghdr header;
struct ifinfomsg body;
};
How do I know which one to use when sending RTM_GETLINK and
RTM_GETADDR requests? Furthermore, it also seems that 'struct rtattr'
can be specified at the end of the request as well. Is there any
documentation that describes this.
