CentOS 7.0 - man page for item_userptr (centos section 3X)

mitem_userptr(3X)								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
       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.
