In all my testing, I couldn't even find one of the "older platforms" where mkstemp used 0666 instead of 0600 - HP-UX 10.20 has broken mkstemp, but still had correct permissions. mkstemps is a newer interface, not yet standardized in POSIX - any platform new enough to implement it is already starting from a decent mkstemp interface. > The answer is fortunately "no".

Which matches the fact that mkstemps is newer. -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
