*
* All three APIs are very similar, however avahi-core is the most powerful.
*
+ * In addition to the three APIs described above Avahi supports two
+ * compatibility libraries:
+ *
+ * \li avahi-compat-libdns_sd: the original Bonjour API as documented
+ * in the header file "dns_sd.h" by Apple Computer, Inc.
+ *
+ * \li avahi-compat-howl: the HOWL API as released with HOWL 0.9.8 by
+ * Porchdog Software.
+ *
+ * Please note that these compatibility layers are incomplete and
+ * generally a waste of resources. We strongly encourage everyone to
+ * use our native APIs for newly written programs and to port older
+ * programs to one of them!
+ *
* \section error_reporting Error Reporting
*
* Some notes on the Avahi error handling:
* avahi_alternative_service_name()) and commit again. Please do not
* free the entry group and create a new one. This would inhibit some
* traffic limiting algorithms in mDNS.
- * - When you need to modify your services, reset the entry group
- * (i.e. avahi_entry_group_reset()) and add them back. Please do not
+ * - When you need to modify your services, use the AVAHI_PUBLISH_UPDATE flag. Please do not
* free the entry group and create a new one. This would inhibit some
* traffic limiting algorithms in mDNS.
*
* for the service type you want to browse for. Use
* avahi_client_resolve_service() to acquire service data for a a service
* name.
- * - You can use avahi_domain_browser() to get a list of announced
+ * - You can use avahi_domain_browser_new() to get a list of announced
* browsing domains. Please note that not all domains whith services
* on the LAN are mandatorily announced.
* - Network monitor software may use avahi_service_type_browser_new()
