menu_format 3X ""
NAME
set_menu_format,
menu_format - set and get menu sizes
SYNOPSIS
#include <menu.h>
int set_menu_format(MENU *menu, int rows, int cols);
void menu_format(const MENU *menu, int *rows, int *cols);
DESCRIPTION
The function set_menu_format sets the maximum display size of the given
menu.
If this size is too small to display all menu items, the menu will be
made scrollable.
If this size is larger than the menus subwindow and the
subwindow is too small to display all menu items, post_menu will fail.
The default format is 16 rows, 1 column. Calling set_menu_format with a null menu pointer will change this default. A zero row or column argument to set_menu_format is interpreted as a request not to change the current value.
The function menu_format returns the maximum-size constraints for the given menu into the storage addressed by rows and cols.
RETURN VALUE
These routines returns one of the following:
5 E_OK The routine succeeded.
5 E_SYSTEM_ERROR System error occurred (see errno(3)).
5 E_BAD_ARGUMENT Routine detected an incorrect or out-of-range argument.
5 E_POSTED The menu is already posted.
5 E_NOT_CONNECTED No items are connected to the menu.
SEE ALSO
curses(3X), menu(3X).
NOTES
The header file <menu.h> automatically includes the header file
<curses.h>.
PORTABILITY
These routines emulate the System V menu library.
They were not supported on
Version 7 or BSD versions.
