Function Documentation

int nl_rtgen_request	(	struct nl_sock *	sk,
		int	type,
		int	family,
		int	flags
	)

Send routing netlink request message.

• sk Netlink socket.
• type Netlink message type.
• family Address family.
• flags Additional netlink message flags.

Fills out a routing netlink request message and sends it out using nl_send_simple().

Returns

0 on success or a negative error code.
