I agree that %05.3:X resulting in 00023 would be ideal. And I agree that we'd have to trim off the 0 modifier before calling the underlying printf %s, and thus be responsible for putting in '0' padding ourselves rather than relying on printf() padding. -- Eric Blake [email protected] +1-801-349-2682 Libvirt virtualization library http://libvirt.org
