void
  
  zip_register_cancel_callback_with_state(zip_t

    callback, void
    (*ud_free)(void *), void
    *ud);
The
    zip_register_cancel_callback_with_state() function
    registers a callback function callback for the zip
    archive archive. The ud_free
    function is called during cleanup for deleting the userdata supplied in
    ud.
The callback function is called during zip_close(3) in regular intervals (after every zip archive entry that's completely written to disk, and while writing data for entries) with zip archive archive and the user-provided user-data ud as arguments. When the callback function returns a non-zero value, writing is cancelled and zip_close(3) returns an error.
The callback function should be fast, since it will be called often.
zip_register_cancel_callback_with_state() was added in
  libzip 1.6.0.
