/*
 *	Name:		add_file.c
 *
 *	Description:	Add a menu file to a menu or a form.  Allocates a
 *		menu file structure using menu_alloc() and initializes the
 *		fields.  Returns a pointer to the menu file, if successful.
 *
 *	Call syntax:	file_p = add_menu_file(obj_p, help, active, name,
 *					       begin_y, begin_x, end_y, end_x,
 *					       gap, path);
 *
 *	Parameters:	pointer		obj_p;
 *			int (*		help)();
 *			char		active;
 *			char *		name;
 *			menu_coord	begin_y;
 *			menu_coord	begin_x;
 *			menu_coord	end_y;
 *			menu_coord	end_x;
 *			menu_coord	gap;
 *			char *		path;
