# menu_userptr 3x 2024-12-28 ncurses 6.5 Library calls

    menu_userptr(3x)                 Library calls                menu_userptr(3x)

## NAME

           set_menu_userptr, 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).

## 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.
