Regarding freeing the json objects.

[venkat]

Hi All,

we are creating json object , json array object etc. how to free those
newly created objects.

eg:

my_array = json_object_new_array();

new_obj = json_object_new_object();

here my_array and new_obj are newly created ones . how to free these
objects.

My doubt is whether it leads to memory leak or not?


Thanks,
Venkat.

If those do not get added to any other object, you need to call json_object_put() on each one.
On the other hand, if you *did* add them to a containing object, then the "ownership" of those objects has transferred over and you need to call json_object_put() on whatever your top-level object is.  That will free all children.

If you need the objects to stick around even after the top-level object is freed, you can manually increase the reference count with json_object_get(), but that is probably not something you want to do.

Hi.

Sorry, folks, can't figure out how do I then delete the root object? :)

Like I said, call json_object_put() on the your top-level (aka root) object.

If you're having problems, please provide a small sample program that demonstrates the issue and we'll see what we can figure out.

Apologies again, the name just really confused me, should've read the docs for the function :)
