NAME    [Toc]    [Back]

       menu_format - set and get menu sizes

SYNOPSIS    [Toc]    [Back]

       #include <menu.h>
       int set_menu_format(MENU *menu, int rows, int cols);
       int menu_format(const MENU *menu, int *rows, int *cols);

DESCRIPTION    [Toc]    [Back]

       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.

RETURN VALUE    [Toc]    [Back]

       These routines returns one of the following:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR    [Toc]    [Back]
            System error occurred (see errno).

       E_BAD_ARGUMENT    [Toc]    [Back]
            Routine detected an incorrect or  out-of-range  argument.


       E_POSTED    [Toc]    [Back]
            The menu is already posted.

SEE ALSO    [Toc]    [Back]

      
      
       curses(3), menu(3).

NOTES    [Toc]    [Back]

       The header file <menu.h> automatically includes the header
       file <curses.h>.

PORTABILITY    [Toc]    [Back]

       These routines emulate the System V  menu  library.   They
       were not supported on Version 7 or BSD versions.
