Manpages - menu_post.3x

post_menu, unpost_menu - write or erase menus from associated subwindows

#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.

*curses*(3X), *menu*(3X).

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.
