You supply the gamepad index (this is the number of "slot" that a gamepad occupies) and select the the trigger to check (left or right). The value returned will be between 0 and 1, where 0 is no pressure on the trigger and 1 full pressure. This returned value will be stored in the target variable that you supply for future use.
