[sane-devel] Knowing ADF source is active

[Kåre Särs]

Hi,

I'm looking into automatically turning on batch scan, in libksane, when the 
scan source is an automatic document feeder. Is there a better way to do it 
than to check if the "source" option is set to "Automatic Document Feeder"?

Is it likely that I will encounter a situation where the scanner is ADF only 
and that the backend doesn't have the "source" option or that the returned 
string isn't "Automatic Document Feeder"?

Thanks,
   Kåre
