40  * This header defines the va_copy variable argument macro, which is
41  * new in ISO C 1999, and thus not present in ISO C 1989 and ISO C++
42  * 1998.  Because this macro is a long-standing Solaris extension, it
43  * is also permitted in other contexts.
44  *
45  * The varargs definitions within this header are defined in terms of
46  * implementation definitions.  These implementation definitions reside
47  * in <sys/va_list.h>.  This organization enables protected use of
48  * the implementation by other standard headers without introducing
49  * names into the users' namespace.
