.TH CURLMOPT_MAXCONNECTS 3 "March 23, 2020" "libcurl 7.73.0" "curl_multi_setopt options"
|
||
|
|
|
||
|
|
.SH NAME
|
||
|
|
CURLMOPT_MAXCONNECTS \- set size of connection cache
|
||
|
|
.SH SYNOPSIS
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_MAXCONNECTS, long max);
|
||
|
|
.SH DESCRIPTION
|
||
|
|
Pass a long indicating the \fBmax\fP. 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 \fICURLOPT_MAXCONNECTS(3)\fP option.
|
||
|
|
|
||
|
|
See \fICURLMOPT_MAX_TOTAL_CONNECTIONS(3)\fP for limiting the number of active
|
||
|
|
connections.
