* @brief Reserve @p size bytes for the underlying buffer
+ * @param size amount of bytes to reserve in the underlying buffer
* @param addInFront if true, then @p size bytes will be available in front (i.e., subsequent call
* to prepend* will not need to allocate memory). If false, then reservation will be done
* at the end of the buffer (i.d., for subsequent append* calls)
