Look at the source code for scanimage, see how it translates SANE_status to exit codes. If that is not sufficient, you might need to catch its STDERR stream, and parse it.
Really, for what you are trying to do, you might be better off interfacing with the SANE API instead of trying to drive scanimage. allan On Sat, Dec 9, 2023 at 2:25 PM Wes Rishel <wris...@gmail.com> wrote: > I have a program that uses SANE to run a Fujitsu fi-5900c scanner, but I > only have access to the scanner when I am doing production work.
