The function returns the length of the placeholder recognized and `strbuf_expand()` skips over it. + +The format `%%` is automatically expanded to a single `%` as a quoting +mechanism; callers do not need to handle the `%` placeholder themselves, +and the callback function will not be invoked for this placeholder. ++ All other characters (non-percent and not skipped ones) are copied verbatim to the strbuf. If the callback returned zero, meaning that the placeholder is unknown, then the percent sign is copied, too. |
