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 connec-
       tions to save time.
