mitem_userptr(3x)                                            mitem_userptr(3x)




NAME

       set_item_userptr, item_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-spe-
       cific  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

       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  sup-
       ported 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.
