menu_userptr(3X)                                              menu_userptr(3X)



NAME
       menu_userptr - associate application data with a menu(3x,n,n tk_menuSetFocus) item

SYNOPSIS
       #include <menu.h>
       int set_menu_userptr(MENU *menu(3x,n,n tk_menuSetFocus), void *userptr);
       void *menu_userptr(const MENU *menu(3x,n,n tk_menuSetFocus));

DESCRIPTION
       Every  menu(3x,n,n tk_menuSetFocus)  and  every  menu(3x,n,n tk_menuSetFocus) 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(7,n,1 builtins) the menu(3x,n,n tk_menuSetFocus) user pointer field.

RETURN VALUE
       Except  for  menu_userptr  (which returns NULL on error(8,n)), each function
       returns one of the following:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
            System error(8,n) occurred (see errno).

SEE ALSO
       curses(3X), menu(3x,n,n tk_menuSetFocus)(3X).

NOTES
       The  header  file(1,n)  <menu.h>  automatically  includes  the  header  file(1,n)
       <curses.h>.

PORTABILITY
       These  routines  emulate the System V menu(3x,n,n tk_menuSetFocus) library.  They were not sup-
       ported on Version 7 or BSD versions.

       The user pointer should be a void pointer.   We  leave  it  as  a  char
       pointer for SVr4 compatibility.
