/*
* An application should not include this header directly. Instead it
* should be included only through the inclusion of other Sun headers.
*
* The purpose of this header is to provide the type definitions for
* the va_list argument used by a number of printf and printf like
* functions. The headers that define these various function prototypes
* #include this header directly. These include but are not necessarily
* limited to <stdio.h>, <stdio_iso.h>, <wchar_iso.h>, <strlog.h> and
* <syslog.h>. The type definitions included in this header are for
* the benefit of consumers of va_list.
*
* Any application that accepts variable argument lists must as documented,
* include either <varargs.h> or the preferred <stdarg.h>. Doing so will
* pull in the appropriate compiler protocols defined in <sys/va_impl.h>
* which is in turn is included by <varargs.h> and <stdarg.h>. See comments
* in <sys/va_impl.h> for more detailed information regarding implementation
* and compiler specific protocols.
*/
/*
* The common definitions exported by this header or compilers using
* this header are:
*
* the identifier __builtin_va_alist for the variable list pseudo parameter
* the type __va_alist_type for the variable list pseudo parameter
* the type __va_list defining the type of the variable list iterator
*
* The feature macros (e.g. __BUILTIN_VA_STRUCT) and compiler macros
* (__GNUC__) and processor macros (e.g. __amd64) are intended to be
* defined by the compilation system, not the user of the system.
