menu_userptr(3)						       menu_userptr(3)

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(3), menu(3).

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.
