Manual Reference Pages - FILE::CHANGENOTIFY::WATCHER::KQUEUE (3)
File::ChangeNotify::Watcher::KQueue - KQueue-based watcher subclass
This class implements watching using IO::KQueue, which must be installed
for it to work. This is a BSD alternative to Linuxs Inotify and similar
Although this watcher is more efficient and accurate than the
File::ChangeNotify::Watcher::Default class, in order to monitor files and
directories, it must open filehandles to each of them. Because many BSD
systems have relatively low defaults for the maximum number of files each
process can open, you may find you run out of file descriptors.
On FreeBSD, you can check (and alter) your systems settings with sysctl if
necessary. The important keys are: kern.maxfiles and
kern.maxfilesperproc. You can see how many files your system current has
open with kern.openfiles.
On OpenBSD, the sysctl keys are kern.maxfiles and kern.nfiles.
Per-process limits are set in /etc/login.conf. See login.conf(5) for
I (Dave Rolsky) cannot test this class, as I have no BSD systems. Reasonable
patches will be applied as-is, and when possible I will consult with Dan
Thomas or other BSD users before releasing.
