No, in practice you must build something which tests for inotify at runtime and falls back to dnotify or even polling. The reason: distributors won't want to build programs which fail to work when run on kernels as recent as 2.6.12 --- at least, not non-system-level programs.
However, this is perfectly doable.

inotify Posted Jul 21, 2006 16:45 UTC (Fri) by cventers (subscriber, #31465) [Link] Ah, good point. Well, at the very least, having build-time inotifysupport would assist some of us (crazy Gentoo users that spend half our lives watching a compiler) immediately and others later ;)
But yes, just attempt inotify at startup. -ENOSYS? Ok, we'll try this
inotify Posted Jul 21, 2006 18:31 UTC (Fri) by nix (subscriber, #2304) [Link] fam 2.7.0 uses dnotify in any case, if it's available. It may not be as nice as inotify but it's a hell of a lot better than polling.
Hm. Looking at the sources, gamin has had an inotify backend since v0.0.8, Aug 26 2004, *long* before inotify hit the kernel proper. It is enabled by default.
Looks like this might be an out-and-out bug. I'll have a look this weekend and see if I can reproduce and fix it.

inotify Posted Jul 23, 2006 17:55 UTC (Sun) by cventers (subscriber, #31465) [Link] True, but this is something that should be part of the desktopinfrastructure, not a part of every application. Most application programmers wouldn't have a lot of fun with Xlib either, but someone's got to do it...
