12# NAME
13
14CURLINFO_NUM_CONNECTS - get number of created connections
15
16# SYNOPSIS
17
18~~~c
19#include <curl/curl.h>
20
21CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_NUM_CONNECTS, long *nump);
22~~~
23
24# DESCRIPTION
25
26Pass a pointer to a long to receive how many new connections libcurl had to
27create to achieve the previous transfer (only the successful connects are
28counted). Combined with CURLINFO_REDIRECT_COUNT(3) you are able to know how
29many times libcurl successfully reused existing connection(s) or not. See the
30connection options of curl_easy_setopt(3) to see how libcurl tries to make
31persistent connections to save time.
