12 bit ADC resolution

On the Arudino 101 home page Arduino Official Store | Boards Shields Kits Accessories

it is mentioned

Analog Inputs. Six of the 20 general purpose I/O pins on the 101 provide analog input. These are labeled A0 through A5, and each provide 10 bits of resolution (i.e. 1024 different values). They measure from ground to 3.3 volts

My question is, since the curie module supports 12 bit A/D resolution, how do I get those 12bit values instead of 10bit values is there a particular API to access the 12bit values?
