   mitem_userptr.3x    ( 3 )

связать данные приложения с пунктом меню (associate application data with a menu item)

Имя (Name)

set_item_userptr, item_userptr - associate application data with a menu item


Синопсис (Synopsis)

#include <menu.h>

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


Описание (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.


Возвращаемое значение (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).

curses(3X), menu(3X).


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.
