CURLMOPT_MAXCONNECTS(3)    curl_multi_setopt options   CURLMOPT_MAXCONNECTS(3)

NAME
       CURLMOPT_MAXCONNECTS - set 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
       maximum amount of simultaneously open connections that libcurl may keep
       in its connection cache after completed use. By default libcurl will
       enlarge 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
       beyond the limit set by you.

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

       This option is for the multi handle's use only, when using the easy
       interface you should instead use the _MAXCONNECTS&section=3">CURLOPT_MAXCONNECTS(3) option.

       See _MAX_TOTAL_CONNECTIONS&section=3">CURLMOPT_MAX_TOTAL_CONNECTIONS(3) for limiting the number of active
       connections.

DEFAULT
