CURLMOPT_MAXCONNECTS(3)             libcurl            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
       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 CURLOPT_MAXCONNECTS(3) option.

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