There used to be a snippet for multi-threaded DNS floating around.. I believe Edwin wrote it? But I can't seem to find it now. My code is here: http://www.divineblood.org/snippets/dnslookup.c It's nothing special. Polling the output of a thread in the existing multiplexer shouldn't be too difficult either. Also, there are quite a few asynchronous DNS libraries floating around. I haven't used any of them, and I don't think any come installed with normal Linux/BSD flavors. But it might be worth checking out. --Palrich. --
