mitem_userptr(3x)                Library calls               mitem_userptr(3x)
       set_item_userptr, item_userptr - associate application data with a menu
       item
       #include <menu.h>
       int set_item_userptr(ITEM *item, void *userptr);
       void *item_userptr(const ITEM *item);
       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.
       The function item_userptr returns a pointer (possibly NULL).   It  does
       not set errno.
       The set_item_userptr always returns E_OK (success).
       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.
