mitem_userptr(3)                Library calls               mitem_userptr(3)


NAME

       set_item_userptr, item_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).


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.
