menu_userptr(3MENU) Library calls menu_userptr(3MENU)
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 func-
tions 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 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.
