menu_userptr(3x)                                       menu_userptr(3x)
NAME
       menu_userptr - associate application data with a menu item
SYNOPSIS
       #include <menu.h>
       int set_menu_userptr(MENU *menu, void *userptr);
       void *menu_userptr(const MENU *menu);
DESCRIPTION
       Every menu and every menu item has a  field  that  can  be
       used to hold application-specific data (that is, the menu-
       driver code leaves it alone).  These functions get and set
       the menu user pointer field.
RETURN VALUE
       Except  for  menu_userptr  (which  returns NULL on error),
       each function returns one of the following:
       E_OK The routine succeeded.
       E_SYSTEM_ERROR
            System error occurred (see errno).
SEE ALSO
       curses(3x), menu(3x).
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.
       The user pointer should be a void pointer.  We leave it as
       a char pointer for SVr4 compatibility.
