FORMS(3)                NetBSD Library Functions Manual               FORMS(3)


NAME

     form_sub, form_win, scale_form, set_form_sub, set_form_win -- form
     library


LIBRARY

     Curses Form Library (libform, -lform)


SYNOPSIS

     #include <form.h>

     WINDOW *
     form_sub(FORM *form);

     WINDOW *
     form_win(FORM *form);

     int
     scale_form(FORM *form, int *rows, int *cols);

     int
     set_form_sub(FORM *form, WINDOW *window);

     int
     set_form_win(FORM *form, WINDOW *window);


DESCRIPTION

     All output to the screen done by the forms library is handled by the
     curses library routines.  By default, the forms library will output to
     the curses stdscr, but if the forms window has been set via
     set_form_win() then output will be sent to the window specified by
     set_form_win(), unless the forms subwindow has been set using
     set_form_sub().  If a subwindow has been specified using set_form_sub()
     then it will be used by the forms library to for screen output.  The cur-
     rent setting for the form window can be retrieved by calling form_win().
     If the forms window has not been set then NULL will be returned.  Simi-
     larly, the forms subwindow can be found by calling the form_sub() func-
     tion, again, if the subwindow has not been set then NULL will be
     returned.  The scale_form() function will return the minimum number of
     rows and columns that will entirely contain the given form.


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:

     E_OK               The function was successful.
     E_NOT_CONNECTED    The form has no fields connected to it.
     E_POSTED           The form is posted to the screen.
