NAME

menu_userptr - associate application data with a menu item  

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

ncurses(3NCURSES), menu(3MENU).  

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.
