IN6_IS_ADDR_MC_INTFACELOCAL MIA?

Well, that’s interesting. If you look at the <netinet6/in6.h> header in the Darwin open source you’ll see it replicates all of the IN6_IS_ADDR_MC_* definitions twice, with the main difference being the the use of a double underscore prefix in the user space variants (which makes sense given C’s rules for platform-specific declarations). However, it seems that IN6_IS_ADDR_MC_INTFACELOCAL was missed from the user space side. This seems like a bug to me and I encourage you to file it as such. Please post your bug number, just for the record.

In the meantime, I think it’s reasonable to just define this yourself.

OK, I will file a report when the feedback server is back online.

I will also add a comment in my code to not be surprised the day the define is back in the header and this creates a conflict with the one I had already defined.

I guess your answer implies that we should use the userland frameworks.
