It's easier than I
Thanks to all for your very useful hints and suggestions.

NetBSD uses the gpio(4) device to talk to the GPIO pins:

NetBSD uses the gpio(4) device to talk to the GPIO pins:
http://man.netbsd.org/gpio.4
So your program opens /dev/gpio and uses ioctl to do things.
Hello!
I successfully installed NetBSD 9.1 evbarm (arm64.img) on a Raspberry Pi
3 B+. In the Raspberry documentation, several example regarding the
handling of GPIO pins are available as Python programs:
https://www.raspberrypi.org/documentation/usage/gpio/python/README.md
They use a module
