Addition/Modification | |
struct nl_msg * | rtnl_class_build_add_request (struct rtnl_class *class, int flags) |
Build a netlink message to add a new class. | |
int | rtnl_class_add (struct nl_handle *handle, struct rtnl_class *class, int flags) |
Add a new class. | |
Cache Management | |
struct nl_cache * | rtnl_class_alloc_cache (struct nl_handle *handle, int ifindex) |
Build a class cache including all classes attached to the specified interface. |
struct nl_msg* rtnl_class_build_add_request | ( | struct rtnl_class * | class, |
int | flags | ||
) | [read] |
class | class to add |
flags | additional netlink message flags |
Builds a new netlink message requesting an addition of a class. The netlink message header isn't fully equipped with all relevant fields and must be sent out via nl_send_auto_complete() or supplemented as needed.

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 next ACK to be received and thus blocks until the request has been processed.
