|
|
<P>That is a strange thing. As far as I experienced in such cases is that
|
|
<BR>
|
|
you can not say which function is used, it may happen that one routine
|
|
<BR>
|
|
uses one function and an other routine uses the other function.
|
|
<BR>
|
|
But after all, when both functions are the same this should work,
|
|
<BR>
|
|
but that really is bad!

|
<BR>
|
|

|
|
</EM><BR>
|

<EM>>
|
|
</EM><BR>
|
|
<EM>> It's not only sanei_wire but also the debug functions. I just did some
|
|
</EM><BR>
|
|
<EM>> changes (locally) to combine all necessary code in debug.c,
|
|
</EM><BR>
|
|
<EM>> store_values.c (load_values, save_values) and wire.c (codec_ascii,
|
|
</EM><BR>
|
|
<EM>> sanei_wire). codec_bin doesn't seem to be needed. Renaming everything
|
|
</EM><BR>
|
|
<EM>> from sanei_w_* to wire_* or something like that works. It's a bigger
|
|
</EM><BR>
|
|
<EM>> change (removing sanei/ completely and most of include/sane). At least
|
|
</EM><BR>
|
|
<EM>> it works :-) I will look at this in more detail tomorrow and post a
|
|
</EM><BR>
|
|
<EM>> patch.
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> I'm not sure, what's the better approach.
|
|
</EM><BR>
|
|
<P>I think this is the correct way to do this.
|
|
<BR>
|
|
<P>If we include it into the backends we have to link it to each backend,
|
|
<BR>
|
|
not only to sane-dll.
|
|
<BR>
|
|
When we make a common lib "libwire" o sthg like that we have to define an
|
|
<BR>
|
|
API for it. It is not part of the sane api.
|
|
<BR>
|
|
<P>Including it into the frontend increases the frontend binary by about 20KB
|
|
<BR>
|
|
(may be less if we look thrugh the code again).
|
|
<BR>
|
|
<P>XSane also uses a reduced set of the sanei_wire... etc routines.
|
|
<BR>
|
|
This way the frotends and backends really work independent in this case
|
|
<BR>
|
|
and I think this is important!
|
|
<BR>
|
|
<P>Bye
