Open a dive computer device for processing. Accepts a context opened with dc_context_new(3), a dive computer descriptor usually found by searching through dc_descriptor_iterator(3), and a iostream opened with a transport specific open function like dc_usbhid_open(3), dc_irda_open(3), dc_serial_open(3), or dc_bluetooth_open(3).
Upon returning DC_STATUS_SUCCESS
, the
device pointer must be freed with
dc_device_close(3).
Returns DC_STATUS_SUCCESS
on success or
one of several error values on error. On success, the
device pointer is filled in with an open handle.
