CURLOPT_MAXCONNECTS(3) curl_easy_setopt options CURLOPT_MAXCONNECTS(3)
NAME
CURLOPT_MAXCONNECTS - maximum connection cache size
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXCONNECTS, long amount);
DESCRIPTION
Pass a long. The set amount will be the maximum number of simultane-
ously 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 and changes libcurl's behavior. 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 CURLOPT_MAXCONNECTS(3) than before may cause open connections
to get closed unnecessarily.
If you add this easy handle to a multi handle, this setting is not ac-
knowledged, and you must instead use curl_multi_setopt(3) and the CURL-
MOPT_MAXCONNECTS(3) option.
DEFAULT
5

curl_easy_setopt(curl, CURLOPT_MAXCONNECTS, 3L);
ret = curl_easy_perform(curl);
}
