Well, the ctime would likely change in those cases, as well as (likely) the inode number and (likely) the size, all of which could be detected via a stat watcher. > >We were talking about timestamp resolution, and what to do about > >it.

So if you want to write an OS X only program, then you should be free to use kqueue, similarly for gnu/linux, but it's not acceptable for libev to become, say, a linux-only library. -- The choice of a Deliantra, the free code+content MORPG -----==- _GNU_ http://www.deliantra.net ----==-- _ generation ---==---(_)__ __ ____ __ Marc Lehmann --==---/ / _ \/ // /\ \/ / p...@goof.com -=====/_/_//_/\_,_/ /_/\_\ _______________________________________________ libev mailing list libev@lists.schmorp.de http://lists.schmorp.de/cgi-bin/mailman/listinfo/libev
