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.
E_NOT_POSTED


The menu has not been posted.
E_NOT_CONNECTED


No items are connected to the menu.
