Enumeration Type Documentation

◆ iio_chan_type

IIO channel type.

A IIO channel has a type specifying the type of data associated with the channel.

◆ iio_event_direction

IIO event direction.

When applicable, this enum specifies the direction of the iio_event_type.

◆ iio_event_type

IIO event type.

Some IIO devices can deliver events. The type of the event can be specified by one of the iio_event_type values.

◆ iio_modifier

IIO channel modifier.

In a addition to a type a IIO channel can optionally have a channel modifier further specifying the data type of of the channel.
