[sane-devel] ADF detection

[Giuseppe Sacco]

Hi all,
I am facing a problem when I use many different scanners. I need to know 
if the scanner source currently used in a scan is ADF or
flatbed.

I noticed that different backends use different names like "FB",
"Flatbed", "ADF", "Automatic Document Feeder".

Is there any way to know that ADF is installed and used? Should I strcmp
all these strings?

Thanks,
Giuseppe
