resolver_srv_rr_new()

resolver_srv_rr_t * resolver_srv_rr_new	(	xmpp_ctx_t *	ctx,
		const char *	host,
		unsigned short	port,
		unsigned short	prio,
		unsigned short	weight
	)

resolver_srv_lookup_buf()

int resolver_srv_lookup_buf	(	xmpp_ctx_t *	ctx,
		const unsigned char *	buf,
		size_t	len,
		resolver_srv_rr_t **	srv_rr_list
	)

Perform lookup for RFC1035 message format.

This function allocates all elements.

Parameters

ctx	a Strophe context object
buf	message in RFC1035 format
len	length of the message
srv_rr_list	is the result

Returns

XMPP_DOMAIN_FOUND on success or XMPP_DOMAIN_NOT_FOUND on fail

resolver_srv_lookup()

int resolver_srv_lookup	(	xmpp_ctx_t *	ctx,
		const char *	service,
		const char *	proto,
		const char *	domain,
		resolver_srv_rr_t **	srv_rr_list
	)

Resolve SRV record.

Parameters

ctx	a Strophe context object
service	service of the SRV record
proto	protocol of the SRV record
domain	resolving domain
srv_rr_list	is the result

Returns

XMPP_DOMAIN_FOUND on success or XMPP_DOMAIN_NOT_FOUND on fail

resolver_srv_free()

void resolver_srv_free	(	xmpp_ctx_t *	ctx,
		resolver_srv_rr_t *	srv_rr_list
	)

Release a list returned by resolver_srv_lookup() or resolver_srv_lookup_buf().

Parameters

ctx	a Strophe context object
srv_rr_list	a list allocated by lookup functions
