This API joins the following two lines: char *s = virBufferContentAndReset(buf1); virBufferAdd(buf2, s, -1); into one: virBufferAddBuffer(buf2, buf1); With one exception: there's no re-indentation applied to @buf1. The idea is, that in general both can have different indentation (like the test I'm adding proves) Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
