If so, can we have this in NetBSD 5.1? (and thanks!)

I think it would be sufficient if __res_check() were exposed and returned a flag indicating wether there was a changed or not. I will want to do some filtering of the search list in some cases, and it'd be better to build up my private modified copy of the search list only when the config changes rather than trying to figure it out on every query. Actually, better yet, return the time of last change instead of a flag. In the case of a threaded program that uses both the getXXX API and the low-level res_XXX api for some reason (perhaps MX lookups or something else not supported at the getXXX level), I guess it's possible that the nss module could end up res_get_state()'ing stale res_states multiple times and re-initing when it doesn't need to.

Yes, that is the point... If resolv.conf changes, programs keep working. If so, can we have this in NetBSD 5.1? (and thanks!) The change is small, but we should test it a few days before pulling it up. christos
