|  | 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
