Constant Summary

READ =

See EVFILT_READ in the kevent(2) man page

INT2NUM(EVFILT_READ)

WRITE =

See EVFILT_WRITE in the kevent(2) man page

INT2NUM(EVFILT_WRITE)

AIO =

See EVFILT_AIO in the kevent(2) man page, not supported by libkqueue

INT2NUM(EVFILT_AIO)

VNODE =

See EVFILT_VNODE in the kevent(2) man page

INT2NUM(EVFILT_VNODE)

PROC =

Monitor process IDs, not supported by libkqueue

INT2NUM(EVFILT_PROC)

SIGNAL =

the use of EvFilt::SIGNAL is NOT supported in Ruby Ruby runtimes already manage all signal handling in the process, so attempting to manage them with a kqueue causes conflicts. We disable the Linux SignalFD interface for the same reason.

TIMER =

See EVFILT_TIMER in the kevent(2) man page

INT2NUM(EVFILT_TIMER)

NETDEV =

network devices, no longer supported

INT2NUM(EVFILT_NETDEV)

INT2NUM(EVFILT_FS)

LIO =

attached to lio requests, not supported by libkqueue
