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.
