FORMS(3) BSD Library Functions Manual FORMS(3)
form_sub, form_win, scale_form, set_form_sub, set_form_win -- form library
Curses Form Library (libform, -lform)
scale_form(FORM *form, int *rows, int *cols);
set_form_sub(FORM *form, WINDOW *window);
set_form_win(FORM *form, WINDOW *window);
All output to the screen done by the forms library is handled by the curses library rou-
tines. 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 subwin-
dow has been specified using 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
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 form_sub() function, again, if the subwindow
has not been set then NULL will be returned. The scale_form() function will return the min-
imum number of rows and columns that will entirely contain the given form.
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.
The header <form.h> automatically includes both <curses.h> and <eti.h>.
