/************************************************************************
	Standard variable argument header.

	va_start	initializes an arg pointer of type va_list.
	va_arg		gets the next argument given its promoted type.
			NOTE: the type cannot be "char" or "short" and
			instead must be the promoted type ("int") for
			such arguments.
	va_end		must be done at the end.

	A function defined to take a variable number of arguments
	should be patterned after:
		#include <stdarg.h>

		int f( int a, char *b, ... ) {  int x; long y;
		    va_list argp;
		    va_start( argp, b );
		       x = va_arg( argp, int );
		       y = va_arg( argp, long );
		    va_end( argp ); }
