Интерактивная система просмотра системных руководств (man-ов) item_userptr (3) item_userptr ( FreeBSD man: Библиотечные вызовы ) >> item_userptr ( Linux man: Библиотечные вызовы )
NAME
mitem_userptr - associate application data with a menu item
SYNOPSIS
#include <menu.h >
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 VALUE
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 (see errno ).
SEE ALSO
curses menu
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.
