Subject: Clarification on rtnetlink requests

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.
