Yes. To summarize, most parameters that were statically defined (in global
variables) are now stored in the htsopt* structure (created by

For example ;

#include "httrack-library.h"
#include "htsopt.h"
#include "htsdefines.h"

httrackp *opt = hts_create_opt();
CHAIN_FUNCTION(opt, init, my_init, /*user-defined arg*/NULL);

Will create a new httrack context, and then chain the "init" callback, using
the my_init function.

The advantage is that you get type some strict checking, because
CHAIN_FUNCTION() is only a macro-definition.

In most public ones (httrack-library.h)

static void __cdecl my_uninit_function(t_hts_callbackarg *carg) {
fprintf(stderr, "bye!\n");
CHAIN_FUNCTION(opt, uninit, my_uninit_function, NULL);
