int rtnl_qdisc_add ( struct nl_sock *  sk,
struct rtnl_qdisc *  qdisc,
int  flags 
)

Add a new qdisc

  • sk Netlink socket.
  • qdisc qdisc to delete
  • flags additional netlink message flags
Builds a netlink message by calling rtnl_qdisc_build_add_request(), sends the request to the kernel and waits for the ACK to be received and thus blocks until the request has been processed.

Common message flags used:

  • NLM_F_REPLACE - replace a potential existing qdisc

Returns:
0 on success or a negative error code
