menu_userptr 3X ""
NAME
menu_userptr - associate application data with a menu item
SYNOPSIS
#include <menu.h>
int set_menu_userptr(MENU *menu, void *userptr);
void *menu_userptr(const MENU *menu);
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.
RETURN VALUE
menu_userptr returns a pointer (which may be NULL).
It does not set errno.
set_menu_userptr returns E_OK (success).
SEE ALSO
curses(3X), menu(3X).
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.
