IIO_EVENT_CODE() - create event identifier : Type of the channel. Should be one of enum iio_chan_type. : Whether the event is for an differential channel or not. : Modifier for the channel. Should be one of enum iio_modifier. : Direction of the event. One of enum iio_event_direction. : Type of the event. Should be one of enum iio_event_type. : Channel number for non-differential channels. : First channel number for differential channels. : Second channel number for differential channels.
