NAME

6       menu_format - set and get menu sizes

SYNOPSIS

9       #include <menu.h>
10       int set_menu_format(MENU *menu, int rows, int cols);
11       void menu_format(const MENU *menu, int *rows, int *cols);
12

DESCRIPTION

14       The function set_menu_format sets the maximum display size of the given
15       menu.  If this size is too small to display all menu  items,  the  menu
16       will  be made scrollable. If this size is larger than the menus subwin‐
17       dow and  the  subwindow  is  too  small  to  display  all  menu  items,
18       post_menu() will fail.
19
20       The  default format is 16 rows, 1 column.  Calling set_menu_format with
21       a null menu pointer will change this default.  A  zero  row  or  column
22       argument  to  set_menu_format is interpreted as a request not to change
23       the current value.
24
25       The function menu_format returns the maximum-size constraints  for  the
26       given menu into the storage addressed by rows and cols.
