связать данные приложения с пунктом меню (associate application data with a menu item)
Имя (Name)
set_menu_userptr, menu_userptr - associate application data with
a menu item
Синопсис (Synopsis)
#include <menu.h>
int set_menu_userptr(MENU *menu, void *userptr);
void *menu_userptr(const MENU *menu);
Описание (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.
Возвращаемое значение (Return value)
menu_userptr returns a pointer (which may be NULL). It does not
set errno.
set_menu_userptr returns E_OK (success).

Примечание (Note)
The header file <menu.h> automatically includes the header file
<curses.h>.
Портативность (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.
