BSD systems typically have their man pages online.

<https://man.openbsd.org/setrlimit> has nothing about it, so I'm assuming
OpenBSD does not have kqueues.

<https://www.freebsd.org/cgi/man.cgi?query=setrlimit&apropos=0&sektion=0&manpath=FreeBSD+11.1-RELEASE+and+Ports&arch=default&format=html>
(the resulting of searching for setrlimit at 
<https://www.freebsd.org/cgi/man.cgi>)
DOES have it, so obviously FreeBSD has them.  Sadly, there is no
link to a kqueue page from the SEE ALSO section.

However, if we search again for kqueue, we get to
<https://www.freebsd.org/cgi/man.cgi?query=kqueue&apropos=0&sektion=0&manpath=FreeBSD+11.1-RELEASE+and+Ports&arch=default&format=html>
which should have all the information you want.

I'd bet you could have got here simply by searching Google for something
like "bsd kqueue man page", though that wasn't the path I chose.
