menu_format(3) Library calls menu_format(3)
NAME
set_menu_format, menu_format - set and get menu sizes
SYNOPSIS
#include <menu.h>
menu_format(3) *menu, int rows, int cols);
menu_format(3) 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.

E_POSTED

E_NOT_CONNECTED

supported on Version 7 or BSD versions.
