 This returns all features of a specific chip. They are returned in bunches: everything with the same mapping is returned just after each other, with the master feature in front (that feature does not map to itself, but has SENSORS_NO_MAPPING as mapping field). nr1 and nr2 are two internally used variables. Set both to zero to start again at the begin of the list. If no more features are found NULL is returned. Do not try to change the returned structure; you will corrupt internal data structures.
