## NAME

           menu_opts - set and get menu options

## SYNOPSIS

           #include <menu.h>
           int set_menu_opts(MENU *menu, OPTIONS opts);
           int menu_opts_on(MENU *menu, OPTIONS opts);
           int menu_opts_off(MENU *menu, OPTIONS opts);
           OPTIONS menu_opts(const MENU *menu);

## DESCRIPTION

           The  function  set_menu_opts  sets  all  the  given menu's
           option bits  (menu  option  bits  may  be  logically-OR'ed
           together).

           The  function menu_opts_on turns on the given option bits,
           and leaves others alone.

           The function menu_opts_off  turns  off  the  given  option
           bits, and leaves others alone.

           The  function  menu_opts returns the menu's current option
           bits.

           The following options are defined (all are on by default):

           O_ONEVALUE
                Only one item can be selected for this menu.

           O_SHOWDESC
                Display  the  item  descriptions  when  the  menu  is
                posted.

           O_ROWMAJOR
                Display the menu in row-major order.

           O_IGNORECASE
                Ignore the case when pattern-matching.

           O_SHOWMATCH
                Move the cursor to within the item  name  while  pat-
                tern-matching.

           O_NONCYCLIC
                Don't   wrap   around  next-item  and  previous-item,
                requests to the other end of the menu.

## RETURN VALUE

           Except for menu_opts, each routine returns one of the fol-
           lowing:

           E_OK The routine succeeded.

           E_SYSTEM_ERROR
                System error occurred (see errno).

           E_POSTED
                The menu is already posted.

## 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.
