@JAYESH TANK
thank you very much :-) that was a very good starting poind :D


@Javier
you are right, so here is something more specific

I want to add a framework for tlv message construction and parsing in
a wireless mesh routing protocol so as it can have the advantages of
the tlv way of communication (one of which is backwards compatibility)

afaik tlvs are used in many places in the kernel and as Jayesh stated
there are no ready made apis.
So if I want to do that I have to copy someone else's code and modify
it accordingly

Hi,

Netlink has some sort of TLV:

nla_put_string(), nla_put_u32(), nla_put_u8(), etc.

But use a socket buffer (struct sk_buff) to store this data. Since you
will use to store and retrieve this info for a networking protocol
(mesh routing), it probably makes sense to reuse Netlink functions.

Take a look to: include/net/netlink.h

Hope it helps,
