  38   40   * The purpose of this header is to provide the type definitions for
  39   41   * the va_list argument used by a number of printf and printf like
  40   42   * functions. The headers that define these various function prototypes
  41   43   * #include this header directly. These include but are not necessarily
  42   44   * limited to <stdio.h>, <stdio_iso.h>, <wchar_iso.h>, <strlog.h> and
  43   45   * <syslog.h>. The type definitions included in this header are for
  44   46   * the benefit of consumers of va_list.
  45   47   *
  46   48   * Any application that accepts variable argument lists must as documented,
  47   49   * include either <varargs.h> or the preferred <stdarg.h>. Doing so will
  48   50   * pull in the appropriate compiler protocols defined in <sys/va_impl.h>
  49   51   * which is in turn is included by <varargs.h> and <stdarg.h>. See comments
  50   52   * in <sys/va_impl.h> for more detailed information regarding implementation
  51   53   * and compiler specific protocols.
