mitem_userptr 3x 2024-12-28 ncurses 6.5 Library calls

mitem_userptr(3x)                Library calls               mitem_userptr(3x)

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.
