SYNOPSIS

#include <menu.h>
int set_menu_userptr(MENU *menu, void *userptr);
void *menu_userptr(const MENU *menu);

DESCRIPTION

Every menu and 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 the menu user pointer field.

RETURN VALUE

Except for menu_userptr (which returns NULL on error), each function returns one of the following: -->
E_OK The routine succeeded.
E_SYSTEM_ERROR
System error occurred (see errno).
