form_win - make and break form window and subwindow associations
int set_form_win(FORM *form, WINDOW *win);
WINDOW *form_win(const FORM *form);
int set_form_sub(FORM *form, WINDOW *sub);
WINDOW *form_sub(const FORM *form);
int scale_form(const FORM *form, int *rows, int *columns);
Every form has an associated pair of curses windows. The form window
displays any title and border associated with the window; the form subwindow
displays the items of the form that are currently available for
The first four functions get and set those windows. It is not necessary
to set either window; by default, the driver code uses stdscr for
In the set_ functions, window argument of NULL is treated as though it
were stsdcr. A form argument of NULL is treated as a request to change
the system default form window or subwindow.
The function scale_form returns the minimum size required for the subwindow
Routines that return pointers return NULL on error. Routines that
return an integer return one of the following error codes:
E_OK The routine succeeded.
E_SYSTEM_ERROR [Toc] [Back]
System error occurred (see errno).
E_BAD_ARGUMENT [Toc] [Back]
Routine detected an incorrect or out-of-range argument.
E_POSTED [Toc] [Back]
The form has already been posted.
E_NOT_CONNECTED [Toc] [Back]
No items are connected to the form.
The header file <form.h> automatically includes the header file
These routines emulate the System V forms library. They were not supported
on Version 7 or BSD versions.
