.SH NAME
|
||
|
|
CURLINFO_NUM_CONNECTS \- get number of created connections
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_NUM_CONNECTS, long *nump);
|
||
|
|
.fi
|
||
|
|
.SH 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 \fICURLINFO_REDIRECT_COUNT(3)\fP you are able to know how
|
||
|
|
many times libcurl successfully reused existing connection(s) or not. See the
|
||
|
|
connection options of \fIcurl_easy_setopt(3)\fP to see how libcurl tries to make
|
||
|
|
persistent connections to save time.
|
||
|
