noble (3) CURLMOPT_MAXCONNECTS.3.gz

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 is used as the maximum amount of simultaneously open
       connections that libcurl may keep in its  connection  cache  after  completed  use.  By  default  libcurl
       enlarges 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.

DEFAULT
