NAME

6       CURLMOPT_MAX_PIPELINE_LENGTH - maximum number of requests in a pipeline
7

SYNOPSIS

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

DESCRIPTION

15       No function since pipelining was removed in 7.62.0.
16
17       Pass  a  long. The set max number will be used as the maximum amount of
18       outstanding requests in an HTTP/1.1 pipeline. This option is only  used
19       for HTTP/1.1 pipelining, not for HTTP/2 multiplexing.
20
21       When  this limit is reached, libcurl will use another connection to the
22       same host (see CURLMOPT_MAX_HOST_CONNECTIONS(3)), or queue the  request
23       until  one  of  the pipelines to the host is ready to accept a request.
24       Thus, the total number of requests in-flight is  CURLMOPT_MAX_HOST_CON‐
25       NECTIONS(3) * CURLMOPT_MAX_PIPELINE_LENGTH(3).
