I think that I have found a mistake in gpiod
https://github.com/brgl/libgpiod/blob/master/lib/core.c#L449
I think that this is comparing two pointers to the same struct. But
they won;t ever match as they are different variables?
Or, alternatively, I don;t understand C and it is fine.
Except it doesn't work....
printf("Chips line 0 %p %s\n", gpiod_line_get_chip(line0),
gpiod_chip_name(gpiod_line_get_chip(line0)));
printf("Chips line 1 %p %s\n", gpiod_line_get_chip(line1),
gpiod_chip_name(gpiod_line_get_chip(line1)));
printf("Chips line 2 %p %s\n", gpiod_line_get_chip(line2),
gpiod_chip_name(gpiod_line_get_chip(line2)));
Returns:
Chips line 0 0x3f1280 gpiochip0
Chips line 1 0x3f2af0 gpiochip0
Chips line 2 0x3f4350 gpiochip0

designed for the especial use of mechanical geniuses, daredevils and
lunatics."
