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). .

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 is a void pointer. We chose not to leave it as a char pointer for SVr4 compatibility.
