IIUC, it needs to match *exactly* the field size inside struct kevent.
So you'll have to use #ifs, possible along with autoconf tests (to
find out the sizes of the fields that typically vary across
implementations).

Here, I would widen the fields to size_t, and use the size_t formatter
(assuming that all systems supporting kqueue also know how to print
size_t, or know to print long long).

Hmm. I think I need to understand the use case better. Can you post
some sample code where this all matters?

If this *is* a regular file-like object, then surely int is enough, no?

Fine with me. The question then is whether long long is available on
all systems that support kqueue.
