NAME


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.

NOTES


The header file <menu.h> automatically includes the header file <curses.h>.

PORTABILITY
