Get the current state of the JSON decoder
#include <sys/json.h>
json_decoder_state_t* json_decoder_get_state(json_decoder_t *decoder);
This function returns the current state of the given decoder. Getting the state allows the decoder to be restored later to that state, with json_decoder_set_state(). The state that is returned is no longer valid following calls to json_decoder_cleanup(), json_decoder_parse_json_str(), or json_decoder_free_state().
A pointer to the current JSON decoder state, or NULL if there was insufficient memory to get the state.
