[sane-devel] sane_set_io_mode and sane_get_select_fd

[m. allan noah]

i assume this is the test backend? the options control the behaviour
of the backend, so that it can act like either a backend that does, or
does not, support those functions, since they are optional. i am not
sure i understand your problem?
