menu_format(3)	    UNIX Programmer's Manual	   menu_format(3)

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 con-
     straints for the given menu into the storage addressed by
     rows and cols.

RETURN VALUE
     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.

SEE ALSO
     curses(3), menu(3).

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

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