I believe there is a misfeature in the DBG() functions. Peter Fales
|
|
<BR>
|
|
pointed out to me that the following code in a backend
|
|
<BR>
|
|
<P> DBG(0, "foo");
|
|
<BR>
|
|
<P>will print out "foo" even if SANE_DEBUG_BACKEND is not set. I believe
|
|
<BR>
|
|
this is wrong. I believe DBG() should not print anything unless
|
|
<BR>
|
|
debugging is enabled for that specific backend. I suggest applying
|
|
<BR>
|
|
this patch to fix it. Is there anything I haven't thought about?
|
|
<BR>
|
|
<P>The patch changes the default level to be (in practise, not in
|
|
<BR>
|
|
reality) -1, instead of the previous default level 0.
