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).
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
