By default, the forms library will output to the curses .Fa stdscr , but if the forms window has been set via .Fn set_form_win then output will be sent to the window specified by .Fn set_form_win , unless the forms subwindow has been set using .Fn set_form_sub . If a subwindow has been specified using .Fn set_form_sub then it will be used by the forms library to for screen output. The current setting for the form window can be retrieved by calling .Fn form_win . If the forms window has not been set then NULL will be returned. Similarly, the forms subwindow can be found by calling the .Fn form_sub function, again, if the subwindow has not been set then NULL will be returned. The .Fn scale_form function will return the minimum number of rows and columns that will entirely contain the given form. .Sh RETURN VALUES Functions returning pointers will return NULL if an error is detected. The functions that return an int will return one of the following error values:
