If we wanted to use size_t, then I'd suggest we added a qemu_strtoXXX variant that directly returned a size_t, and did suitabled bounds checking > But I'm not overly concerned either way, so Agreed, doesn't need fixing now > Reviewed-by: Richard Henderson <r...@twiddle.net> Regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :|
