Do you need the extra (), or will one of these shorter forms also work? if (!tmp && size * count != 0) if (!tmp && (size * count) != 0) -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3266 Virtualization: qemu.org | libvirt.org

if (!tmp && size * count != 0) if (!tmp && (size * count) != 0)
I feel the extra () aid in readability, because you don't have to try to remember precedence rules which many people don't remember accurately.
