Hi,

I'm just trying to get my question across so on purpose I'm skipping some
code or error checks here and focusing on the relevant pieces.
I am posting data to services vi the CURLOPT_READFUNCTION and am using
curl_multi_perform. I have also used the trace and dump snippet on the
website and pasted the output below. So the issue I am facing is that, when
curl_multi_perform is called, I see that requestWriter function is not
called and the content is empty - Any idea?

int handles = 2;

for(int i =0 ; i < handles; i++) {
     CURL *curl = curl_easy_init();

     CURLcode cc = curl_easy_setopt(curl, CURLOPT_URL, url);

      if (debug) {
          curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);
          curl_easy_setopt(curl, CURLOPT_DEBUGFUNCTION, my_trace);
          curl_easy_setopt(curl, CURLOPT_DEBUGDATA, alldata[i]);
     }

       curl_easy_setopt(curl, CURLOPT_HEADERFUNCTION, headerWriter);
       curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, responseBody);
       curl_easy_setopt(curl, CURLOPT_WRITEDATA, alldata[i]);
       //curl_easy_setopt(curl, CURLOPT_READFUNCTION, requestWriter);
       //curl_easy_setopt(curl, CURLOPT_READDATA, alldata[i]]);
        curl_easy_setopt(curl, CURLOPT_POST, 1);

Just a debugging thing to verify..
        vector<struct CurlParams>::iterator it;
        cout << "req vector contains: "<<endl;
        for ( it=alldata.begin() ; it < alldata.end(); it++ ) {
          cout << "Status: " << (*it).httpStatus<<endl;
          cout << "Postbody: " << (*it).postbody<<endl;
          cout << "Posturl: " << (*it).posturl<<endl;
          cout << "Postrem: " << (*it).postrem<<endl;
       }

      cmc = curl_multi_add_handle(mh, curl);
} //end of for;

int nRunning;
cout<"Calling multiperform for handle %s", url.c_str());
        //usleep(5000);
        int ncalls = 1;

while ((cmc = curl_multi_perform(mh, &nRunning)) ==
CURLM_CALL_MULTI_PERFORM) {
            cout<<"curl_multi_perform():%s, nRunning=%d:Calling again",
curl_multi_strerror(cmc), nRunning";
            ncalls++;
 }

..

}

output..
