NAME
menu_post - 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.
