39 * ISO C 1999.  It does not follow the namespace rules for ISO C++
40 * 1998.  For legacy support, it also defines the pre-standard variable
41 * argument definitions.
42 *
43 * The varargs definitions within this header are defined in terms of
44 * implementation definitions.  These implementation definitions reside
45 * in <sys/va_impl.h>.  This organization enables protected use of
46 * the implementation by other standard headers without introducing
47 * names into the users' namespace.
