[sane-devel] ADF scanning

[Rayudu Addagarla]

Hello
when one uses adf scanner.
what does a backend return the each page is done.
say i use, scanadf -s1 -e3

After each page is done a backend returns what SANE_STATUS??
i know that at the end backend should return SANE_STATUS_NO_DOCS

how will scanadf know that each page scanning is done and again continue fot
the next untill NO_DOCS.
Is there any detailed document for writing a backed for ADF scanner

thanks
