24 * The result of the call is delivered to the 'callback' function with the 'callback_closure'.
26 * For convenience, the function calls 'json_object_put' for 'args'.
27 * Thus, in the case where 'args' should remain available after
28 * the function returns, the function 'json_object_get' shall be used.
30 * The 'callback' receives 3 arguments:
31 * 1. 'closure' the user defined closure pointer 'callback_closure',
32 * 2. 'status' a status being 0 on success or negative when an error occured,
33 * 2. 'result' the resulting data as a JSON object.

39 * @param callback The to call on completion
