Re: YAJL Parser... getting a pointer to the data and length of the data?

Ok, I think I get it now. :)

If I pass a size into yajl_get_string_buf() then where would the cleanup
happen?

The way I'm doing it now, I do the cleanup after I'm done working with it.
So, for each JSON element I allocate the space, do my work with the data,
then deallocate the space.

If I call this 100 times (passing in a size and not allocating and
deallocating) and the cleanup doesn't happen until the end that could be a
LOT of allocated space. And right now the only cleanup I see is
deallocating the main tree using yajl_tree_free(node);

So, I think we have similar ideas, but different methods.

Oh hey, Brad, your page
(http://www.fieldexit.com/forum/display?threadid=321) shows this:

data@ = %alloc(MAX_SIZE);

So, you do have *some* kind of limit, and that limit is known in the
calling RPG before you do

rc = yajl_get_string_buf(val:data@);

It's pretty darn big in 7.1 (docs say 4GB if teraspace is used).
Presumably that's enough. So, to make your call compatible with
Scott's version of YAJL_GET_STRING_BUF() (note that he said he agreed
with you on returning the string length), wouldn't you just do

rc = yajl_get_string_buf(val:data@:MAX_SIZE);

?

If that suffices for your needs, then I retract my earlier idea of
including both versions (yours and Scott's) and endorse Scott's
(caller passes pointer to pre-allocated buffer; procedure returns the
string length instead of just a flag).

Or do you have another way to call it which really does need fully
dynamic operation?
