Future status:

  • NABTO_CLIENT_EC_OK if opening went ok
  • NABTO_CLIENT_EC_NOT_FOUND if requesting an unknown service
  • NABTO_CLIENT_EC_FORBIDDEN if target device did not allow opening a tunnel to specified service for the current client
  • NABTO_CLIENT_EC_STOPPED if the tunnel is stopped.
  • NABTO_CLIENT_EC_NOT_CONNECTED if the connection is not established yet.
  • NABTO_CLIENT_EC_PRIVILEGED_PORT if the connection is not established because the port is privileged and the user does not have access to start a listening socket on that port number.
