NAME

set_item_userptr, item_userptr - associate application data with a menu item

CONTENTS

SYNOPSIS

#include <menu.h>
int set_item_userptr(ITEM *item, void *userptr);
void *item_userptr(const ITEM *item);

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

The function item_userptr returns a pointer (possibly NULL). It does not set errno.

The set_item_userptr always returns E_OK (success).

SEE ALSO

curses(3), menu(3).

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 is a void pointer. We chose not to leave it as a char pointer for SVr4 compatibility.

On two occasions I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.
