mitem_userptr 3X ""
NAME
mitem_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
Except for item_userptr (which returns NULL on error), each function returns one of the following:

5 E_OK The routine succeeded.

5 E_SYSTEM_ERROR System error occurred (see errno).

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 should be a void pointer. We leave it as a char pointer for SVr4 compatibility.
