NAME

CURLINFO_NUM_CONNECTS - get number of created connections

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_NUM_CONNECTS, long *nump);

DESCRIPTION

Pass a pointer to a long to receive how many new connections libcurl had to create to achieve the previous transfer (only the successful connects are counted). Combined with CURLINFO_REDIRECT_COUNT(3) you are able to know how many times libcurl successfully reused existing connection(s) or not. See the connection options of curl_easy_setopt(3) to see how libcurl tries to make persistent connections to save time.

  res = curl_easy_perform(curl);


  if(res == CURLE_OK) {


    long connects;


    res = curl_easy_getinfo(curl, CURLINFO_NUM_CONNECTS, &connects);


    if(res)


      printf("It needed %d connects\n", connects);


  }


  curl_easy_cleanup(curl);
}
