    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
         Except for item_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.
