menu_post() -- write or erase menus from associated subwindows

SYNOPSIS

#include <menu.h>

int post_menu(MENU *menu);

int unpost_menu(MENU *menu);

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.
