|

tinysvcmdns
|
||||
============
|
||||
tinysvcmdns is a tiny MDNS responder implementation for publishing services.
|
||||
|
||||
This implementation is only concerned with publishing services, without a
|
||||
system-wide daemon like Bonjour or Avahi. Its other goal is to be extremely
|
||||
small, embeddable, and have no external dependencies.
|
||||
|
||||
It only answers queries related to its own hostname (the A record), the
|
||||
service PTRs, and the "_services.dns-sd._udp.local" name, which advertises
|
||||
all services on a particular host.
|
||||
|
||||
Services consist of a single SRV and TXT record.
|
||||
|
||||
Decoding of MDNS packets is only done to retrieve the questions and answer RRs.
|
||||
The purpose for decoding answer RRs is to make sure the service PTR is not
|
||||
sent out if it is already included in the answer RRs.
|
||||
|
||||
It also only utilizes multicast packets, so no "QU" queries are accepted.
|
||||
|
||||
There is no name collision detection, so this means no queries are generated
|
||||
before publishing the services. However compliant responders will avoid using
|
||||
our names, since the implementation will respond to queries that match our
|
||||
name.
|
||||
|
||||
|
||||
TODO
|
||||
-----
|
||||
* better, more stable & complete API
|
||||
* name collision detection
|
||||
|
||||
|
||||
FILES
|
||||
------

||||
* mdns.c - provides data structures, parsing & encoding of MDNS packets
|
||||
* mdnsd.c - implements the server socket, communication and thread
|
||||
* testmdnsd.c - an example that creates an instance until terminated
