mitem_userptr(3X)                                          mitem_userptr(3X)

NAME         top

       set_item_userptr,  item_userptr  -  associate application data with a
       menu item

SYNOPSIS         top

       #include <menu.h>
       int set_item_userptr(ITEM *item, void *userptr);
       void *item_userptr(const ITEM *item);

DESCRIPTION         top

       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         top

       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         top

       curses(3X), menu(3X).

NOTES         top

       The header file <menu.h> automatically includes the header file
       <curses.h>.

PORTABILITY         top

       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.
