Indeed, I will change in the next iteration.
And looking into above line, this whole construction I would prefer to have a macro in minmax.h like
#define min_array(array, len) \ {( \ typeof(len) __len = (len); \ typeof(*(array)) __element = (array)[--__len]; \ while (__len--) \ __element = min(__element, (array)[__len]); \ __element; \ )}
(it might need more work, but you got the idea)
}break;

default:/* FIXME: learn about min for other iio values */I believe in a final version this comment won't be here.
We have the same FIXME comment in the iio_channel_read_max() function I copied to create this iio_channel_read_min() and, to be honest, I don't really know how to handle these other cases.
In this series, I would prefer to keep this FIXME.
I see, Jonathan needs to be involved here then.
