< p > < b > XXX< / b > this shouldn't use internal fields: Trailing characters after the parsed value do not automatically cause an error. It is up to the caller to decide whether to treat this as an error or to handle the additional characters, perhaps by parsing another json value starting from that point.< / p >
< p > Extra characters can be detected by comparing the tok-> char_offset against the length of the last len parameter passed in.< / p >
< p > The tokener does < b > not< / b > maintain an internal buffer so the caller is responsible for calling json_tokener_parse_ex with an appropriate str parameter starting with the extra characters.< / p >
< p > This interface is presently not 64-bit clean due to the int len argument so the function limits the maximum string size to INT32_MAX (2GB). If the function is called with len == -1 then strlen is called to check the string length is less than INT32_MAX (2GB)< / p >
