Netlink is not without complexities:
Netlink is a socket family (similar to AF_INET or AF_UNIX ) but with the address family AF_NETLINK . It provides a datagram-oriented messaging service using the standard socket API ( socket() , bind() , sendmsg() , recvmsg() ). What makes Netlink unique is that it allows user-space processes to communicate with kernel subsystems (and even between user-space processes using multicast) in a reliable, asynchronous manner. He could crumble it
In exchange, sitting on his desk, heavy and real, lay a small, clay tablet containing a cure for a disease that hadn't existed for a thousand years.
On the screen, the text changed.
: Adding a new Netlink protocol family is straightforward using macros like genl_register_family() .
