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
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(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. AUTHORS
