This can also fail and you should check the return code and print an error
message if it does.

As far as i understood, the "gpiod_set_array_value_cansleep(...)"
function doesn't return
anything, it will return immediately if gpios->desc is null but nothing
else.
Did i miss something?

No I did, sorry about that.

We *should* make these functions return errors but currently they do not.

Error codes?

Same question here, these functions only make call to
"gpiod_set_value_cansleep(...)",
which as far as i understood doesn't return any error code.

Yeah, forget that.

Here too.

Same question, doesn't seem to have an error code.

That too.
