Re: SK YAJL functions - JSON objecst as attributes' values

My fault. I didn't realize I had to set the new length after having copied
the buffer.
Thank you

Hi all,
Just a question about YAJL_copyBuf as I am not able to determine the
correct size of the buffer.
It seems like the buffer length remains set to the larger one, so when a
new copy is done of a shorter number of bytes it always copies the

previous

amount of data, meaning the result data contains garbage at the end.
I made lots of tries (like using %len(%trim(xxx)) instead of %size or
getting a buffer pointer a then using the returned length) but I can't
make it working and I am running out of time.
That's the code:
dcl-s jsonData char(32000);
dcl-s wRetLen int(10:0) inz;
dcl-s CCSID int(10:0) inz(0); // 0=job CCSID, 1208=utf-8
clear jsonData;
clear wRetLen;
YAJL_genOpen( *off );
YAJL_beginObj();
YAJL_addBool('success' : stdOutput.success);
YAJL_addChar('errCode' : stdOutput.errCode);
YAJL_addChar('message' : stdOutput.message);
YAJL_addBool('missingData' : stdOutput.missingData);
// stdOutput.data is already a JSON object
YAJL_addPreformattedPtr(
'data'
: %addr(stdOutput.data: *DATA)
: %len(%trimr(stdOutput.data))
);
YAJL_endObj();
YAJL_copyBuf(CCSID
: %addr(jsonData)
: %size(jsonData)
: wRetLen);
YAJL_genClose();
response.body = %trim(jsonData);
response.status = HTTP_OK;

Thank you very much for any help.

@Charles, you are right, but despite the many tries there are times,
which I couldn't focus, where using varchar doesn't work as expected;
that's the reason trim functions are present in the code.
But I'll try again.

And hopefully, if stdOutput.data is built properly without trailing
blanks...

She can get rid of the %trimr()...

YAJL_addPreformattedPtr('data'
: %addr(stdOutput.data:*DATA)
: %len(stdOutput.data);

Correct, this is what yajl_addPreformattedPtr() is meant for.

If I understand Maria's original post, though, the first parameter
should not be omitted because this is being added as a field named
'data' in an object. So the code would look something like this:

YAJL_beginObj();
YAJL_addBool('success' : stdOutput.success);
YAJL_addChar('errCode' : stdOutput.errCode);
YAJL_addChar('message' : stdOutput.message);
YAJL_addPreformattedPtr('data'
: %addr(stdOutput.data:*DATA)
: %len(%trimr(stdOutput.data));
YAJL_endObj();

Looks like you would *Omit the first parameter then supply the

pointer

to the reformatted string plus its length in the third parm - which

doesn't

show up in the prototype doc but is present in the actual proto.
