struct rtnl_rule *  tmpl,
int  flags 
)

Add a new rule

  • sk Netlink socket.
  • tmpl template with requested changes
  • flags additional netlink message flags
Builds a netlink message by calling rtnl_rule_build_add_request(), sends the request to the kernel and waits for the next ACK to be received and thus blocks until the request has been fullfilled.

Returns:
0 on sucess or a negative error if an error occured.
