linuxrtnetlinkh
linuxrtnetlinkh is the conventional shorthand for the Linux kernel header file include/linux/rtnetlink.h. This header provides the definitions and structures used by the rtnetlink portion of the Netlink interface, which the kernel and user-space networking tools rely on to manage networking state.
The rtnetlink interface is the kernel’s API for configuring and querying network-related objects such as interfaces,
Key structures and facilities in the header include the rtmsg structure, which encapsulates information about a
linuxrtnetlinkh thus serves as the canonical source for programmers writing kernel code or user-space programs that
