CURLMOPT_MAXCONNECTS(3)    curl_multi_setopt options   CURLMOPT_MAXCONNECTS(3)

NAME
       CURLMOPT_MAXCONNECTS - size of connection cache

SYNOPSIS
       #include <curl/curl.h>

       CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_MAXCONNECTS, long max);

DESCRIPTION
       Pass a long indicating the max. The set number will be used as the max‐
       imum amount of simultaneously open connections that libcurl may keep in
       its  connection  cache after completed use. By default libcurl will en‐
       large the size for each added easy handle to make it fit  4  times  the
       number of added easy handles.

       By setting this option, you can prevent the cache size from growing be‐
       yond the limit set by you.

       When the cache is full, curl closes the oldest one in the cache to pre‐
       vent the number of open connections from increasing.

       This option is for the multi handle's use only, when using the easy in‐
       terface you should instead use the CURLOPT_MAXCONNECTS(3) option.

       See CURLMOPT_MAX_TOTAL_CONNECTIONS(3) for limiting the number of active
       connections.
