menu_userptr(3MENU)													       menu_userptr(3MENU)

NAME
       mitem_userptr - associate application data with a menu item

SYNOPSIS
       #include <menu.h>
       int set_item_userptr(ITEM *item, void *userptr);
       void *item_userptr(const ITEM *item);

DESCRIPTION
       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 that field.

RETURN VALUE
       The function item_userptr returns a pointer (possibly NULL).  It does not set errno.

       The set_item_userptr always returns E_OK (success).

SEE ALSO
       ncurses(3NCURSES), menu(3MENU).

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 is a void pointer.  We chose not to leave it as a char pointer for SVr4 compatibility.
