* [[system call]]{{snd}} is a function to facilitate programs to request services from the kernel
**<tt>[[File descriptor|eventfd()]]</tt>
** [[netlink]]{{snd}} socket family used for IPC between kernel and user space processes, designed as the successor of <tt>[[ioctl]]</tt>; Netlink was added by [[Alan Cox]] during Linux kernel 1.3 development as a character driver interface to provide multiple kernel and user-space bidirectional communications links. Then, Alexey Kuznetsov extended it during Linux kernel 2.1 development to provide a flexible and extensible messaging interface to the new advanced routing infrastructure. Since then, Netlink sockets have become one of the main interfaces that kernel subsystems provide to user-space applications in Linux. Modern [[Wireless network interface controller|WNIC]][[Comparison of open-source wireless drivers|drivers]] use it to communicate with user-space.
