mitem_userptr() -- associate application data with a menu item

SYNOPSIS

#include <menu.h>

int set_item_userptr(ITEM *item, const void *userptr);

const 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 VALUES

Except for item_userptr() (which returns NULL on error), each function returns one of the following:

E_OK: The routine succeeded.
E_SYSTEM_ERROR: System error occurred.

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 should be a void pointer. We leave it as a char pointer for SVr4 compatibility.
