mitem_userptr(3x)                                     mitem_userptr(3x)

NAME

       mitem_userptr  -  associate  application  data with a menu
       item

SYNOPSIS

       #include <menu.h>
       int set_item_userptr(ITEM *item, void *userptr);
       void *item_userptr(const ITEM *item);

DESCRIPTION

       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 that field.

RETURN VALUE

       Except  for  item_userptr  (which  returns NULL on error),
       each function returns one of the following:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
            System error occurred (see errno).

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