<P>
|
|
<EM>> some backends do return invalid pointers when sane_get_option_descriptor
|
|
</EM><BR>
|
|
<EM>> is called with a negative option (if only tests for <max_options and not for >=0).
|
|
</EM><BR>
|
|
<P><EM>> Please could every backend author make sure that only a valid pointer or NULL
|
|
</EM><BR>
|
|
<EM>> is returned.
|
|
</EM><BR>
|
|
<P>Just fixed the Artec backend so it returns NULL if ( option >= NUM_OPTIONS )
|
|
<BR>
|
|
or if ( option < 0 ). Will hopefully commit to cvs tonight after I finish
|
|
<BR>
|
|
fixing another bug I'm working on.
