Re: [pdf-devel] Public API and gl_list

[jemarch]

   Ok, I finally got the new API working.
   There are some changes for the API documentation though. Functions
   pdf_list_iterator() and pdf_list_iterator_from_to() may fail when calling
   pdf_alloc() so the caller must check for the NULL value before using it.

No problem. We can change the documentation in gnupdf.texi.

    inline pdf_status_t
    pdf_list_iterator_free (pdf_list_iterator_t *iterator)
    {
   -  gl_list_iterator_free (iterator);
   +  gl_list_iterator_free ((gl_list_iterator_t*)(iterator->gl_iterator));
   +
   +  pdf_dealloc (iterator->gl_iterator);
   +
      return PDF_OK;
    }

Is that `pdf_dealloc' on iterator->gl_iterator ok? I think that the
previous `gl_list_iterator_free' call is disposing the memory pointed
by iterator->gl_iterator.
