item_userptr3menu
Associate application data with a menu item
Part of menu_userptr(3menu).
Usage
#include <menu.h>
int set_item_userptr(ITEM *item, void *userptr); void *item_userptr(const ITEM *item);
Overview
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.
