A user came to me recently with the following problem, and since I've never
written anything using varargs, I'm stumped.

The user wants to pass a variable number of arguments to a function like
printf, like this:

#include <curses.h>

WINDOW	*window1;

dprintf(a,b,s,va_alist)
int	a,b;
char	*s;
va_dcl
{
	wmove(window1, a, b);
	wprintw(window1, s, va_alist);
}

First off, can you do something like this?  Secondly, I doubt that I have
the syntax right.  Can someone point me in the right direction?
