mg_dns_send_reply()	mg_dns_send_reply	func	void mg_dns_send_reply(struct mg_connection *nc, struct mg_dns_reply *r);

Sends a DNS reply through a connection.

The DNS data is stored in an IO buffer pointed by reply structure in r. This function mutates the content of that buffer in order to ensure that the DNS header reflects the size and flags of the message, that might have been updated either with mg_dns_reply_record or by direct manipulation of r->message.

Once sent, the IO buffer will be trimmed unless the reply IO buffer is the connection's send buffer and the connection is not in UDP mode.
