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.
