A generic helper function for dynamically sizing columns would indeed be nice, but I think that can be a follow up. It would require callers to allocate a char*** - an array rows to be formatted, where each row is represented by an array of columns. I'm okay with Daniel's patch going in now, as it is a strict improvement, even if we make further improvements down the road. -- Eric Blake ebl...@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
