CURLINFO_NUM_CONNECTS

Section: curl_easy_getinfo options (3)
Updated: May 06, 2017

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.  

PROTOCOLS

EXAMPLE

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);
}
