Title Body

I am writing a program that downloads multiple files (at the moment its only 2). I am trying to get it to display a progress bar for each download using the ProgressFunction callback. The problem I am running into is I cannot figure out a way to differentiate between the progress between the two files. Right now it is switching between the two. I have tried looking for any further documentation but it seems the API link is broken on their site and there is not much other than some basic examples. //ProgressCalback double ProgressCallBack(double dltotal, double dlnow, double ultotal, double ulnow){ double progress = (dlnow/dltotal) * 100; std::ostringstream strs; float percent = floorf(progress * 100) / 100; strs << percent; printf("%s\t%d\t%d\t%d\t%d\n", strs.str().c_str(),dltotal, dlnow, ultotal, ulnow); return 0; }; curlpp::options::ProgressFunction progressBar(ProgressCallBack); request1.setOpt(new curlpp::options::Url(url1)); request1.setOpt(new curlpp::options::Verbose(false)); request1.setOpt(new curlpp::options::NoProgress(0)); request1.setOpt(progressBar); I am not entirely sure what part of my code would be relevant so here are the parts pertaining to the progress callback. Any help would be appreciated.
