menu_post.3x man page

post_menu, unpost_menu — 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(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.

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 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.

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.
