menu_userptr(3X)														  menu_userptr(3X)

NAME
       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).

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.
