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-spe-
       cific 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:

       E_OK The routine succeeded.

       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 sup-
       ported on Version 7 or BSD versions.

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