rfc3596BuildAAAAQuery()

ssize_t rfc3596BuildAAAAQuery	(	const char *	hostname,
		char *	buf,
		size_t	sz,
		unsigned short	qid,
		rfc1035_query *	query
	)

Builds a message buffer with a QUESTION to lookup AAAA records for a hostname. Caller must allocate 'buf' which should probably be at least 512 octets. The 'szp' initially specifies the size of the buffer, on return it contains the size of the message (i.e. how much to write).

Returns

the size of the query
