set_menu_format, menu_format - set and get menu sizes
#include <menu.h>
int set_menu_format(MENU *menu, int rows, int cols);
void 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.
These routines returns one of the following:
E_OK The routine succeeded.
E_SYSTEM_ERROR
System error occurred (see errno).
E_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argument.
E_POSTED
The menu is already posted.
E_NOT_CONNECTED
No items are connected to the menu.
curses(3X), menu(3X).
The header file <menu.h> automatically includes the header file
<curses.h>.
These routines emulate the System V menu library. They were not
supported on Version 7 or BSD versions.
