NAME

6       CURLMOPT_MAXCONNECTS - set size of connection cache
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLMcode  curl_multi_setopt(CURLM  *handle, CURLMOPT_MAXCONNECTS, long
12       max);
13

DESCRIPTION

15       Pass a long indicating the max. The set number will be used as the max‐
16       imum amount of simultaneously open connections that libcurl may keep in
17       its connection cache after  completed  use.  By  default  libcurl  will
18       enlarge  the size for each added easy handle to make it fit 4 times the
19       number of added easy handles.
20
21       By setting this option, you can prevent the  cache  size  from  growing
22       beyond the limit set by you.
23
24       When the cache is full, curl closes the oldest one in the cache to pre‐
25       vent the number of open connections from increasing.
26
27       This option is for the multi handle's use only,  when  using  the  easy
28       interface you should instead use the CURLOPT_MAXCONNECTS(3) option.
29
30       See CURLMOPT_MAX_TOTAL_CONNECTIONS(3) for limiting the number of active
31       connections.
