Hello, While writing the backend, I noticed so far only plustek backend seems to employ sanei_access for locking the device. Since in multi user systems it is possible that accidentally someone else might try to access a scanner in use, I think using the locking mechanism provided by sanei_access would make sense.
I added locking to my cs3200f backend and got it working quite easily and reliably (checked also automatic deletion of locks for the killed processes). SANE_DEBUG_SANEI_ACCESS=255 was very helpful in figuring out the place of the lock file. What are other's opinions about this? Should locking be a recommended practice? With best regards, Lauri Pirttiaho Oulu Finland ................................................................... Luukku Plus paketilla p??set eroon tila- ja turvallisuusongelmista.
