Hey, What are the *handler and *data_ready function pointers in 'struct netlink_opt' for? I mean, if data_ready is for the function that will process the received messages, then handler does what? struct netlink_opt { ... int (*handler)(int unit, struct sk_buff *skb); .. void (*data_ready)(struct sock *sk, int bytes); } -Ankit - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
