CURLINFO_NUM_CONNECTS - get number of created connections #include <curl/curl.h> CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_NUM_CONNECTS, long *nump); 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. All

CURL *curl = curl_easy_init();
if(curl) {
 CURLcode res;
 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
 curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
 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);
}

Added in 7.12.3 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. curl_easy_getinfo "(3), " curl_easy_setopt "(3), "
