Userspace access to IIO
The sysfs attributes are documented in sysfs-bus-iio.
Udev will create the following entries under /dev by default:
device0:buffer0:access0 - ring access chrdev
device0:buffer0:event0 - ring event chrdev
device0:event0 - general event chrdev.
The files, lis3l02dqbuffersimple.c and iio_utils.h in this directory provide an example
of how to use the ring buffer and event interfaces.
