iio_buffer length

[Denis Ciocca <denis.ciocca@gmail.com>]

Hi guys,

I finally managed to resolve the issues about iio_trigger and iio_buffer.
Now I ask please you if you can clarify to me about use of
iio_generic_buffer and how I can use the /dev/iio:deviceX char-event
to catch data from buffer.
I compiled the generic-buffer program and I don't understand how datas
come out. My driver has 4 channels:
- 3 for accelerometer raw data (x,y,z)
- 1 for timestamp

The application set up the length of buffer to 32, but when I run the
application I don't see 32 samples but only 16. What means 32?
It is possible the use of buffer to catch every sample? (buffer length = 1)?
When I set buffer length to 1 the application doesn't work!

Thanks,
Denis
