gen_netlink is a encoder, decoder and tool library for talking to the Linux kernel netlink interface.
gen_netlink uses gen_socket to create a netlink socket and wrap that socket in a gen_udp port for ease of use. For Erlang R15 and greater a recent gen_socket is required.
Using rebar:
# rebar get-deps
# rebar compile
The encoder and decoder logic is generated using priv/decode_gen.escript. The resulting file is included in release archive and the repository to simplify the build process.
