# mitem_userptr 3x 2023-11-25 ncurses 6.4 Library calls

    mitem_userptr(3x)                Library calls               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-
           specific  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).

## PORTABILITY

           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.
