2 * lib/msg.c Netlink Messages Interface
15 * Netlink Message Construction/Parsing Interface
21 * Netlink messages consist of a byte stream with one or multiple
22 * Netlink headers and an associated payload. If the payload is too big
23 * to fit into a single message it, can be split over multiple Netlink
26 * Netlink header flag set, except for the last header which has the
27 * Netlink header type \c NLMSG_DONE.
30 * The Netlink message header (\link nlmsghdr struct nlmsghdr\endlink) is shown below.
46 * The netlink message header and payload must be aligned properly:
67 * alignment and formatting rules depening on the specific netlink
78 * @par The ACK Netlink Message
87 * | Netlink message header |
92 * | OLD Netlink message header |
98 * // Various methods exist to create/allocate a new netlink
101 * // nlmsg_alloc() will allocate an empty netlink message with
111 * // Alternatively an existing netlink message header can be used
119 * // Last but not least, netlink messages received from netlink sockets
122 * // length of the existing netlink message, therefore no more data can
129 * // NLMSG_ALIGNTO to ensure proper netlink message padding.
