<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>

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