The first thing I ran into was how to convert gpioSetSignalFunc. The rough parallel seems to be gpiod_ctxless_event_monitor. One difference I see right off, however, is that I used to be able to end monitoring events from a particular pin by passing in a null callback.
The documentation for gpiod_ctxless_event_monitor shows no indication of a way to terminate callbacks. I'll see what happens if I press on hoping that pass null callbacks does the trick, but it's going to be a while until the code I'm writing is ready to test, so if I can get a definitive answer before eventually learning the hard way, that would be much appreciated.
I'm certain to have more questions as I proceed (like how to deal with not yet seeing any equivalent to gpioGlitchFilter).
