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.
