menu_post(3X) menu_post(3X) NAME menu_post - write(1,2) or erase menus from associated subwindows SYNOPSIS #include <menu.h> int post_menu(MENU *menu(3x,n,n tk_menuSetFocus)); int unpost_menu(MENU *menu(3x,n,n tk_menuSetFocus)); DESCRIPTION The function post_menu displays a menu(3x,n,n tk_menuSetFocus) to its associated subwindow. To trigger physical display of the subwindow, use refresh or some equiva- lent 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(3x,n,n tk_menuSetFocus) from its associated subwindow. RETURN VALUE These routines return one of the following: E_OK The routine succeeded. E_SYSTEM_ERROR System error(8,n) occurred (see errno). E_BAD_ARGUMENT Routine detected an incorrect or out-of-range argument. E_POSTED The menu(3x,n,n tk_menuSetFocus) 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 to use set_menu_format() to solve the problem. E_NOT_POSTED The menu(3x,n,n tk_menuSetFocus) has not been posted. E_NOT_CONNECTED No items are connected to the menu. SEE ALSO curses(3X), menu(3x,n,n tk_menuSetFocus)(3X). NOTES The header file(1,n) <menu.h> automatically includes the header file(1,n) <curses.h>. PORTABILITY These routines emulate the System V menu(3x,n,n tk_menuSetFocus) library. They were not sup- ported on Version 7 or BSD versions. AUTHORS Juergen Pfeifer. Manual pages and adaptation for new curses by Eric S. Raymond. menu_post(3X)
