# NAME
|
||
|
|
|
||
|
|
CURLINFO_NUM_CONNECTS - get number of created connections
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#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.
