menu_format - set and get menu sizes
#include <menu.h>
int set_menu_format(MENU *menu, int rows, int cols);
int menu_format(const MENU *menu, int *rows, int *cols);
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.
