/*
 *	Name:		add_noecho.c
 *
 *	Description:	Add a noecho to a form.  Allocates a form noecho
 *		structure using menu_alloc() and initializes the noechos.
 *		Returns a pointer to the form noecho.
 *
 *	Call syntax:	noecho_p = add_form_noecho(form_p, help, active,
 *						     name, y_coord, x_coord,
 *						     data_p, data_size,
 *						     pre_func, pre_arg,
 *						     post_func, post_arg);
 *
 *	Parameters:	form *		form_p;
 *			int (*		help)();
 *			char		active;
 *			char *		name;
 *			menu_coord	y_coord;
 *			menu_coord	x_coord;
 *			char *		data_p;
 *			int		data_size;
 *			int (*		pre_func)();
 *			pointer		pre_arg;
 *			int (*		post_func)();
 *			pointer		post_arg;
 *
 *	Return value:	form_noecho *	noecho_p;
