* Note: when using the buffered writer, cbopaque is passed to write_cb only
* when the buffer is flushed. It would make a difference if cbopaque points
* to something that's changing for each write_cb call, or something that
* affects write_cb in a way dependent on the content of the output string.
* However, the most typical usage case in practice is that cbopaque points to
* some "option like" content for the write_cb, so it doesn't matter.
