|
|
.SH NAME
|
|
|
|
|
CURLMOPT_MAX_TOTAL_CONNECTIONS \- max simultaneously open connections
|
|
|
|
|
.SH SYNOPSIS
|
|
|
|
|
#include <curl/curl.h>
|
|
|
|
|
|
|
|
|
|
CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_MAX_TOTAL_CONNECTIONS, long amount);
|
|
|
|
|
.SH DESCRIPTION
|
|
|
|
|
Pass a long for the \fBamount\fP. The set number will be used as the maximum
|
|
|
|
|
number of simultaneously open connections in total using this multi
|
|
|
|
|
handle. For each new session, libcurl will open a new connection up to the
|
|
|
|
|
limit set by \fICURLMOPT_MAX_TOTAL_CONNECTIONS(3)\fP. When the limit is
|
|
|
|
|
reached, the sessions will be pending until there are available
|
|
|
|
|
connections. If \fICURLMOPT_PIPELINING(3)\fP is enabled, libcurl will try to
|

|
|
|
pipeline or use multiplexing if the host is capable of it.
|
2014-11-04 04:31:24 -05:00
|
|
|
.SH DEFAULT
|
|
|
|
|
The default value is 0, which means that there is no limit. It is then simply
|
|
|
|
|
controlled by the number of easy handles added.
