<EM>> The definition of sane_get_option_descriptor says:
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> "... The returned option descriptor is guaranteed to remain valid (and
|
|
</EM><BR>
|
|
<EM>> at the returned address) until the device is closed." (SANE Standard
|
|
</EM><BR>
|
|
<EM>> Version 1.01, page 26, 4.3.6 sane_get_option_descriptor)
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> Since the constraint range is part of the option descriptor it may not

|
|

Hi,
|
|
<BR>
|
|
I just didn't know that valid == elements remain unchanged.
|
|
<BR>
|
|
I thought this only refers to the pointer... my fault :-(
|
|
<BR>
|
|
<P>Thanks for your reply,
|
|
<BR>
|
|
