</PRE>
<H2>NAME</H2><PRE>
       <STRONG>menu_format</STRONG> - set and get menu sizes


</PRE>
<H2>SYNOPSIS</H2><PRE>
       <STRONG>#include</STRONG> <STRONG>&lt;menu.h&gt;</STRONG>
       int set_menu_format(MENU *menu, int rows, int cols);
       void menu_format(const MENU *menu, int *rows, int *cols);


</PRE>
<H2>DESCRIPTION</H2><PRE>
       The function <STRONG>set_menu_format</STRONG> 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, <STRONG>post_menu()</STRONG> will
       fail.

       The  default  format  is  16  rows,  1  column.    Calling
       <STRONG>set_menu_format</STRONG>  with a null menu pointer will change this
       default.  A zero row or column argument to <STRONG>set_menu_format</STRONG>
       is  interpreted  as  a  request  not to change the current
       value.

       The function <STRONG>menu_format</STRONG>  returns  the  maximum-size  con-
       straints  for the given menu into the storage addressed by
       <STRONG>rows</STRONG> and <STRONG>cols</STRONG>.


</PRE>
<H2>RETURN VALUE</H2><PRE>
       These routines returns one of the following:

       <STRONG>E_OK</STRONG> The routine succeeded.

       <STRONG>E_SYSTEM_ERROR</STRONG>
            System error occurred (see <STRONG>errno</STRONG>).

       <STRONG>E_BAD_ARGUMENT</STRONG>
            Routine detected an incorrect or  out-of-range  argu-
            ment.

       <STRONG>E_POSTED</STRONG>
            The menu is already posted.

       <STRONG>E_NOT_CONNECTED</STRONG>
            No items are connected to the menu.

       file <STRONG>&lt;curses.h&gt;</STRONG>.


</PRE>
<H2>PORTABILITY</H2><PRE>
       These routines emulate the System V  menu  library.   They
       were not supported on Version 7 or BSD versions.
