Hello,
I've been using SIP to wrap a closed source binary SDK for Linux I have, with
quite a bit of success considering I don't know much of C++ (Kudos to the SIP
team!).
Now I have a slight problem that I'm not sure to address so I'm wondring if
someone could point me in the right direction.
I have the following signature:
LT_STATUS getDataByIndex(lt_uint32 index, const LTIMetadataRecord*& record)
const;
Everything here is fine, except for that *& notation which I haven't come
across before.
The example C++ code does something like this to use this method:
for (i=0; i<numRecs; i++)
{
const LTIMetadataRecord* rec = NULL;
sts = db.getDataByIndex(i, rec);
ASSERT(LT_SUCCESS(sts));
dumpRecord(*rec);
}
The problem for me is that LTIMetadataRecord does NOT have constructors. So
I'm not sure what to pass getDataByIndex() for the second parameter.
I tried something like:
record = None
db.getDataByIndex(index, record)
print record
But "record" remains unchanged. Of course, I can't create an instance of
LTIMetadataRecord, so I'm not sure how else to go about this.
Any have an idea, or ideally, a recipe? (Or maybe there's an example of
something like this in PyQT/PyKDE?)
Any help would be much appreciated!
Thanks in advance,
Jean-François Doyon
