Not really.. you have 2 main implementations - avahi,  

both are available on many platforms.. some for example avahi is not  
available on windows but mDNSResponder is.. but neither is installed  
by default or even commonly.

avahi is much more common on linux, mDNSResponder is on osx.. etc.

the only common library i know between the two is I think KDE's mDNS  
interface which has an avahi plugin and mDNSResponder plugin but i  
have no idea what the state of that is and I believe it is quite tied  
to KDE libraries.

I would love to promote using Avahi API natively but if you wrote for  
mDNSResponder - Avahi has a compatibility library to use Avahi with  
the same API calls.. but it is a bit ugly to rely on it rather than  
using it for existing programs.
