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).

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.

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

These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.
