/**
 * Set initial size allocation for memory when creating strings,
 * as is done for example in fjson_object_to_json_string(). The
 * default size is 32, which is very conservative. If an app
 * knows it typically deals with larger strings, performance
 * can be improved by setting the initial size to a different
 * number, e.g. 1k. Note that this also means that memory
 * consumption can increase. How far entriely depens on the
 * application and its use of json-c.
 *
 * Note: each time this function is called, the initial size is
 * changed to the given value. Already existing elements are not
 * affected. This function is usually meant to be called just once
 * at start of an application, but there is no harm calling it more
 * than once. Note that the function is NOT thread-safe and must not
 * be called on different threads concurrently.
 *
 * @param size new initial size for printbuf (formatting buffer)
