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.
