NAME
       CURLMOPT_MAX_PIPELINE_LENGTH - maximum number of requests in a pipeline

SYNOPSIS
       #include <curl/curl.h>

       CURLMcode    curl_multi_setopt(CURLM    *handle,     CURLMOPT_MAX_PIPE-
       LINE_LENGTH, long max);

DESCRIPTION
       Pass  a  long. The set max number will be used as the maximum amount of
       outstanding requests in an HTTP/1.1 pipelined connection.  This  option
       is only used for HTTP/1.1 pipelining, not for HTTP/2 multiplexing.

       When  this limit is reached, libcurl will use another connection to the
       same host (see CURLMOPT_MAX_HOST_CONNECTIONS(3)), or queue the  request
       until  one  of  the pipelines to the host is ready to accept a request.
       Thus, the total number of requests in-flight is  CURLMOPT_MAX_HOST_CON-
       NECTIONS(3) * CURLMOPT_MAX_PIPELINE_LENGTH(3).

DEFAULT
       5

PROTOCOLS
       HTTP(S)
