scan_mask
- [INTERN] bitmask used in masking scan mode elements
scan_timestamp
- [INTERN] does the scan mode include a timestamp
access
- [DRIVER] buffer access functions associated with the implementation.
scan_el_dev_attr_list
- [INTERN] list of scan element related attributes.
buffer_group
- [INTERN] attributes of the buffer group
scan_el_group
- [DRIVER] attribute group for those attributes not created from the iio_chan_info array.
pollq
- [INTERN] wait queue to allow for polling on the buffer.
stufftoread
- [INTERN] flag to indicate new data.
attrs
- [INTERN] standard attributes of the buffer
demux_list
