menu_userptr(3x)                                              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).

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.
