please find how I am using httrack

	httrackp* opt = hts_create_opt();

	CHAIN_FUNCTION(opt, end, httrack_wrapper_end_431, NULL);	
	CHAIN_FUNCTION(opt, check_link, httrack_wrapper_check_431, NULL);
	CHAIN_FUNCTION(opt, check_html, httrack_wrapper_checkhtml_431, NULL);
	CHAIN_FUNCTION(opt, linkdetected, httrack_wrapper_linkdetected_431, NULL);

	/* Then, launch the mirror */
	int ret = hts_main2(argc, argv, opt);

	/* Clear option state */
	hts_free_opt(opt);
	hts_uninit();
