  xmlStopParser is not the right thing, the terminate flag is the one
indicating the end. There is some sample code in xmllint.c in the
source distribution:

                    ctxt = xmlCreatePushParserCtxt(NULL, NULL,
                                chars, res, filename);
                    xmlCtxtUseOptions(ctxt, options);
                    while ((res = fread(chars, 1, size, f)) > 0) {
                        xmlParseChunk(ctxt, chars, res, 0);
                    }
                    xmlParseChunk(ctxt, chars, 0, 1);
                    doc = ctxt->myDoc;
                    ret = ctxt->wellFormed;
                    xmlFreeParserCtxt(ctxt);
                    if (!ret) {
                        xmlFreeDoc(doc);
                        doc = NULL;
                    }

  it would be useful to build a clean example for push to integrate
in the set of examples http://xmlsoft.org/examples/index.html
