Does Kqueue need close like epoll?

Does Kqueue handler need close ? I mean :

int hd = epoll_create(512);
  ....
  close(hd); // we have to close

so for kqueue, does it need Close ?

int hd = kqueue();
  ...
  close(hd) ? // is this a must ?

Yes.

Kqueue uses a file descriptor, exactly like epoll, meaning that it should be closed when you're done with it.

Mostly, the OS cleanup will close it if you didn't do so before the process terminated... however, this is considered a bad practice.
