Function kevent

pub unsafe fn kevent<Fd: AsFd, Buf: Buffer<Event>>(
    kqueue: Fd,
    changelist: &[Event],
    eventlist: Buf,
    timeout: Option<Duration>,
) -> Result<Buf::Output>

kevent(kqueue, changelist, eventlist, timeout)—Wait for events on a kqueue.

This is a wrapper around kevent_timespec which takes a Duration instead of a Timespec for the timemout value. Timespec has a signed i64 seconds field; if converting Duration to Timespec overflows, None is passed as the timeout instead, such such a large timeout would be effectively infinite in practice.

Safety

The file descriptors referred to by the Event structs must be valid for the lifetime of the kqueue file descriptor.
