    I apologize for this message but I dont understand the following test:

    in snapscan.c
    function sane_open

                pss->devname = strdup (name);
                if (!name)
                {
                    free (*h);
                    DBG (DL_MAJOR_ERROR,
                         "%s: out of memory copying device name.\n",
                         me);
                    return SANE_STATUS_NO_MEM;
                }

    Why are you testing 'name' and not pss->devname?
    name is the first function argument.

    I don't understand also why in this function a temporary file is created and
    unlinked but closed later... and some write can may be happen! The file
    will be destroyed when closing but in the same source file it is a little
    strange (but should work).
