NAME

       File::ChangeNotify::Watcher::KQueue - KQueue-based watcher subclass

DESCRIPTION

       This class implements watching using IO::KQueue, which must be installed for it to work. This is a BSD alternative to Linux's Inotify and
       similar event-based systems.

CAVEATS

       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 system's 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
       details.

SUPPORT

       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.
