mitem_userptr(3x)                                     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).
       curses(3x), menu(3x).
       The header file <menu.h> automatically includes the header
       file <curses.h>.
       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.
