File::ChangeNotify::WaUserrContributed PFile::ChangeNotify::Watcher::KQueue(3)NAMEFile::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".
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.
