> + * Formats a size (for example the size of a file) into a human readable

> + * and are displayed rounded to the nearest tenth. E.g. the file size

> + * This string should be freed with g_free() when not needed any longer.

> + * See g_format_size_full() for more options about how the size might be
> + * formatted.
