menu_format (3X)                                                                              menu_format (3X)



NAME
       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.
