.TH CURLOPT_MAXCONNECTS 3 "17 Jun 2014" libcurl libcurl
|
|
.SH NAME
|
|
CURLOPT_MAXCONNECTS \- maximum connection cache size
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXCONNECTS, long amount);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
Pass a long. The set \fIamount\fP is the maximum number of simultaneously open
|
|
persistent connections that libcurl may cache in the pool associated with this
|
|
handle. The default is 5, and there is not much point in changing this value
|
|
unless you are perfectly aware of how this works. This concerns connections
|
|
using any of the protocols that support persistent connections.
|
|
|
|
When reaching the maximum limit, curl closes the oldest one in the cache to
|
|
prevent increasing the number of open connections.
|
|
|
|
If you already have performed transfers with this curl handle, setting a
|
|
smaller \fICURLOPT_MAXCONNECTS(3)\fP than before may cause open connections to
|
|
get closed unnecessarily.
|
|
|
|
If you add this easy handle to a multi handle, this setting is not
|
|
acknowledged, and you must instead use \fIcurl_multi_setopt(3)\fP and the
|
|
\fICURLMOPT_MAXCONNECTS(3)\fP option.
