23 .TH CURLMOPT_MAXCONNECTS 3 "17 Jun 2014" "libcurl 7.37.0" "curl_multi_setopt options"
24 .SH NAME
25 CURLMOPT_MAXCONNECTS \- set size of connection cache
26 .SH SYNOPSIS
27 #include <curl/curl.h>
28
29 CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_MAXCONNECTS, long max);
30 .SH DESCRIPTION
31 Pass a long indicating the \fBmax\fP. The set number will be used as the
32 maximum amount of simultaneously open connections that libcurl may keep in its
33 connection cache after completed use. By default libcurl will enlarge the size
34 for each added easy handle to make it fit 4 times the number of added easy
35 handles.
36
37 By setting this option, you can prevent the cache size from growing beyond the
38 limit set by you.
39
40 When the cache is full, curl closes the oldest one in the cache to prevent the
41 number of open connections from increasing.
42
43 This option is for the multi handle's use only, when using the easy interface
44 you should instead use the \fICURLOPT_MAXCONNECTS(3)\fP option.
45
46 See \fICURLMOPT_MAX_TOTAL_CONNECTIONS(3)\fP for limiting the number of active
47 connections.
