/*
 *	Name:		add_yesno.c
 *
 *	Description:	Add a yes/no question to a form.  Allocates a yes/no
 *		structure using menu_alloc() and initializes the fields.
 *		Returns a pointer to the yes/no structure.
 *
 *	Call syntax:	yesno_p = add_form_yesno(form_p, help, active, name,
 *						 y_coord, x_coord,
 *						 answer_p,
 *						 pre_func, pre_arg,
 *						 no_func, no_arg,
 *						 yes_func, yes_arg);
 *
 *	Parameters:	form *		form_p;
 *			int (*		help)();
 *			char		active;
 *			char *		name;
 *			menu_coord	y_coord;
 *			menu_coord	x_coord;
 *			char *		answer_p;
 *			int (*		pre_func)();
 *			pointer		pre_arg;
 *			int (*		no_func)();
 *			pointer		no_arg;
 *			int (*		yes_func)();
 *			pointer		yes_arg;
