Or to rephrase, qemu acts as though it uses GNU getopt_long_only() (some programs like gcc do likewise), but MOST programs that take long opts behave like they use getopt_long(). It is only the getopt_long_only() variant that accepts long options with a single dash, when it is unambiguous with POSIX getopt() parsing of multiple smashed-together short options. [well, qemu rolls its own option parser instead of using getopt_long_only(), but you get the picture] -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
