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 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() 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.
