post(3menu)


NAME

   post_menu,   unpost_menu   -  write  or  erase  menus  from  associated
   subwindows

SYNOPSIS

   #include <menu.h>
   int post_menu(MENU *menu);
   int unpost_menu(MENU *menu);

DESCRIPTION

   The function post_menu displays a menu to its associated subwindow.  To
   trigger  physical  display  of  the  subwindow,  use  refresh  or  some
   equivalent curses routine (the implicit doupdate triggered by an curses
   input  request  will  do). post_menu resets the selection status of all
   items.

   The function unpost_menu erases menu from its associated subwindow.

RETURN VALUE

   These routines return 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 has already been posted.

   E_BAD_STATE
        Routine was called from an initialization or termination function.

   E_NO_ROOM
        Menu is too large for its  window.  You  should  consider  to  use
        set_menu_format() to solve the problem.

   E_NOT_POSTED
        The menu has not been posted.

   E_NOT_CONNECTED
        No items are connected to the menu.

SEE ALSO

   ncurses(3NCURSES), menu(3MENU).

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.
