DC_DEVICE_OPEN(3) Library Functions Manual DC_DEVICE_OPEN(3)

open a dive computer device

library “libdivecomputer”

#include <libdivecomputer/device.h>
dc_device_open(dc_device_t **device, dc_context_t *context, dc_descriptor_t *descriptor, dc_iostream_t *iostream);

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.

dc_context_new(3), dc_descriptor_iterator(3), dc_device_close(3)
