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

PROTOCOLS
       Most

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         CURLcode ret;
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
         /* limit the connection cache for this handle to no more than 3 */
         curl_easy_setopt(curl, CURLOPT_MAXCONNECTS, 3L);
         ret = curl_easy_perform(curl);
       }

AVAILABILITY
       Always

RETURN VALUE
       Returns CURLE_OK
