post_menu, unpost_menu - write or erase menus from associated subwindows

SYNOPSIS DESCRIPTION RETURN VALUE SEE ALSO NOTES PORTABILITY AUTHORS

#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(3X) 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.

These routines return one of the following:

E_OK	The routine succeeded.
E_SYSTEM_ERROR
	System error occurred (see errno(3)).
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 using 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.

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

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