14# NAME
15
16CURLINFO_NUM_CONNECTS - get number of created connections
17
18# SYNOPSIS
19
20~~~c
21#include <curl/curl.h>
22
23CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_NUM_CONNECTS, long *nump);
24~~~
25
26# DESCRIPTION
27
28Pass a pointer to a long to receive how many new connections libcurl had to
29create to achieve the previous transfer (only the successful connects are
30counted). Combined with CURLINFO_REDIRECT_COUNT(3) you are able to know how
31many times libcurl successfully reused existing connection(s) or not. See the
32connection options of curl_easy_setopt(3) to see how libcurl tries to make
33persistent connections to save time.

35# EXAMPLE

37~~~c
38int main(void)
39{
40  CURL *curl = curl_easy_init();
41  if(curl) {
42    CURLcode res;
43    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
44    curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
45    res = curl_easy_perform(curl);
46    if(res == CURLE_OK) {
47      long connects;
48      res = curl_easy_getinfo(curl, CURLINFO_NUM_CONNECTS, &connects);
49      if(res)
50        printf("It needed %ld connects\n", connects);
51    }
