/* Helper routine for building cJSON objects in a printf-like manner.
**
** Sample call:
** j = iperf_json_printf("foo: %b bar: %d bletch: %f eep: %s", b, i, f, s);
**
** The four formatting characters and the types they expect are:
** %b boolean int
** %d integer int64_t
** %f floating point double
** %s string char *
** If the values you're passing in are not these exact types, you must
** cast them, there is no automatic type coercion/widening here.
**
** The colons mark the end of field names, and blanks are ignored.
**
** This routine is not particularly robust, but it's not part of the API,
** it's just for internal iperf3 use.
